=============================================================================
Version 3.2 Final (Aug 22, 1997)
=============================================================================

GENERAL NOTE:
 	Because Unisys Corp. has stated that they will not charge royalties for
 	the use of the LZW compression algorithm in *FREE* programs, xfig will
 	continue to support importing and exporting of GIF images.
 	However, be aware that if you sell xfig, for example as part of a CD-ROM
 	package with freeware, you may be liable for paying royalties to Unisys.
 	You may comment out the USEGIF variable in the Imakefile to avoid this.
 	With USEGIF commented out, xfig will still import GIF files, but not
 	export in that format.  Also, for screen capture, xfig will create a PCX
	file instead of a GIF file.
 	*** The authors of xfig and the Lawrence Berkeley National Laboratory
 	cannot be held responsible in any case. ***

NOTE:	fig2dev now handles the exporting to bitmap formats (GIF, JPEG etc)
	  instead of xfig, so there is more consistent output. Requires the
	  netpbm package and ghostscript.  See the README file.

NEW FEATURES:
	o Japanese text objects (i18n) availble using flag I18N in Imakefile
	    from T.Sato (VEF00200@niftyserve.or.jp)
	o ppm, tiff (no compression) and AutoCad (acad) output languages added
	o image quality (0-100) is selectable for JPEG export
	o figure size (in inches or cm) is shown in the export and print panels,
	  taking into account current magnification
	o "Fit to page" button sets magnification so that figure size will just
	  fill current paper size with (at least) 1/2 inch margin all around
	o emergency save file renamed from xfig.SAVE to SAVE.fig
	o when doing a screen capture for a picture object, the filename of
	  the capture is the name of the figure file + the time according
	  to time(3) + .gif, e.g. myfigure_858367466.gif
	o xfig version number in app-defaults file is checked and warning
	    message appears if older than current version
	o spell checker to find misspelled words in text objects
	    from T.Sato (VEF00200@niftyserve.or.jp)
	o search and replace - search for strings and either replace them with
	    new string or update settings like color, etc. on matched strings
	    from T.Sato (VEF00200@niftyserve.or.jp)
	o exporting to pstex does both PostScript and LaTeX part in one step
	    to file.pstex and file.pstex_t respectively
	o popup messages (balloons): 
	    o describes drawing/editing function when mouse passes over
	      any drawing/editing button 
	    o describes how to activate unit/scale popup when mouse passes over
	      units box (where the rulers meet)
	    o describes mouse function indicator when mouse passes over it
	    o describes each command button in top row as mouse passes over
	      buttons
	    o toggle button labelled "Balloons" to turn on/off the balloon
	      messages
	   o all have configurable colors; see Fig-color.ad
	o new figures in Examples directory from Bill Chimiak (chim@bgsm.edu):
		1. clp_computer1.fig - computer equipment clipart
		2. clp_hospit_equip.fig - hospital equipment clipart
		3. clp_network.fig - updated network equipment clipart
		4. musicnotes.fig - musical notes, scale lines and clef
	o checks version number in app-default file with xfig version and warns
	   if file is older

BUGS FIXED:
	o arrowheads on splines didn't always point correctly (fig2dev did the
	  right thing, though)
	o accomodation for 15-bit visual (believe it or not!)
	o checks bits-per-pixel for image formats because some vendors use 32 bits
	  for 24 bit depths
	o minor difference in A0 and A1 page sizes
	o changed XPM variables to default X include/library in Imakefile
	o path added to save filename when xfig makes emergency save
	o incorrect email address for xfig-bugs in man page (should be
	  xfig-bugs@epb1.lbl.gov)
	o typo about font_flags bit number for LaTeX vs PostScript in
	  Doc/FORMAT3.2 file
	o not enough space allocated for buf[] in create_print_panel()
	  and create_export_panel()
	  from T.Sato (VEF00200@niftyserve.or.jp)
	o typo in Doc/FORMAT3.2 file about header information in Fig files
	o typo in man pages - zooming uses only CONTROL key, changing spline
	  shape factor requires both CONTROL and SHIFT keys.
	o justification and page size are now disabled with EPS export
	o undo of converting spline to line caused seg fault
	o added #ifdef USE_GIF around transparent color in export and read file
	o error in sprintf format (was %4.2lf - should be %4.2f) in bottom
	  indicator panel buttons that have floats
	  from T.Sato (VEF00200@niftyserve.or.jp)
	o center of pie-wedge style arc wasn't included in bounding box
	  from Andy Thomas (alt@picnic.demon.co.uk)
	o better handling of mouse function indicator
	  from T.Sato (VEF00200@niftyserve.or.jp)
	o if "edit spline point" panel is popped up before general edit panel,
	  'Warning: Action not found: apply' appeared when edit panel was
	  later opened
	  from T.Sato (VEF00200@niftyserve.or.jp)
	o actions that had same names renamed to unique names
	  from T.Sato (VEF00200@niftyserve.or.jp)
	o mouse button 1 and 3 didn't scroll the H, S, or V sliders in the color
	  edit panel
	o unsigned/signed char pointer mix in create_pic_pixmap and
	  get_canvas_clipboard
	o cleanup of dictionary wrapped around imported EPS files 
	  from Franz Koch (franz.koch@zdv.uni-tuebingen.de)
	o Portrait/Landscape changes didn't properly toggle width/height
	o New font specified in app-defaults for those systems whose default
	  font was too large for popup panels (Fig*Font: 7x13bold)
	o Zooming not allowed if drawing object in progress (panning is OK)
	o strcasecmp and strncasecmp bugs (s2 != '\0' and s2 == '\0' should
	  be *s2 ...)
	o when exporting to bitmap format, bounding box of figure was rounded
	  to current point positioning grid (unintended)
	o unaligned access errors on 64-bit machines (e.g. Alpha) when importing
	  bitmap pictures.  Now uses unsigned int for pointers
	o code to remove identical consecutive points in line objects had bug
	o workaround for long-time Intrinsics bug with scrolling text widget in
	  viewport for file and export lists provided by 
	  Mark London (mrl@psfc.mit.edu)
	o bug in control-key-button-1 zoom sequence - didn't allow control key
	  pressed when completing zoom operation
	o mis-named fonts for zapf chancery and zapf dingbats (many servers don't
	  have these fonts anyway so please don't ask me where to get them)
	o error in JPEGINC variable in Imakefile - had leading "/" in path
	o width of "open compound" button was slightly too large such that 
	  the mode panel (left) obscured part of the indicator panel (bottom)
	  when -but_per_row was 3
	o transparent color for GIF export wasn't "None" as default
	o box objects read in from Fig file would only have three points on
	  some machines
	o grid wasn't changed to metric when loading metric figure
	o 24- and 32-bit export to JPEG was incorrect
	o "rotate and copy" for text placed first copy correctly, but subsequent
	  copies incorrectly
	o comments after #FIG before end of header weren't parsed correctly
	o Landscape/Portrait is only available for PostScript export
	o Ledger/Tabloid sizes reversed (Tabloid is 11x17", Ledger is 17x11")
	o deleting all objects (Meta-D) prevented the "New figure" function
	  by keeping the original figure name
	o arrowheads were inadvertantly allowed for closed splines via the popup
	  edit panel

	o picture objects rotated 90 or 270 degrees were also flipped
	o changed sense of USEINLINE so default is NOT to use it

--------------------------
V3.2 Beta 1 (Jan, 9, 1997)
--------------------------

NEW EXAMPLE FILES (Examples/ directory)

    o fantastic figure from Robort Ford (rford@mailserv.mta.ca):
	transit.fig	- transit map of Saint John, New Brunswick (Canada)
			  Don't use it for locating transit routes - it is only
			  good through July 1996 and only shows non-rush-hour
			  routes
    o great figures from Carlo Kopp (carlo@cs.monash.edu.au):
	greenpig.fig	- F/RF-111C/G Tactical Fighter
	rfxc.fig	- RFX Strike/Recon Fighter
	lidar.fig	- Sidelooking battlefield surveillance LIDAR
	sowpig.fig	- RAAF F-111C fighter jet w/ 2x AGM-142 Have Nap SOWs
    o some nice figures from Peter Hiscocks (phiscock@ee.ryerson.ca)
	aircraft.fig	- light aircraft
	ps-foil.fig	- power supply circuit board foil layout
	ps-foil.fig	- power supply circuit board schematic
    o from Philipp Reisner (Austria).  
	Linuxlogo.fig	- the only entry in the Linux 2.0 Logo contest to be
			  rendered with xfig - Unfortunately, it didn't win :-(
    o new clip art objects from W. Chimiak (chim@tachyon.medeng.wfu.edu):
	clp_computer.fig - various computers, monitors etc.
	clp_network.fig	- computer network components
    o more new example files (done by me, Brian Smith)
	3dhouse.fig	- cutaway view of a simple house drawn in 3D
	ctrlbox_lay.fig	- dimensioned drawing of a control box for a project in my group
	ctrlbox_sch.fig	- electrical schematic of the control box

NEW FEATURES

o better error reporting from ghostscript when importing EPS files
o in color popop panel, "lookup color" button allows user to grab color from
	any window for user-defined color in xfig
	uses code from xpaint (Copyright 1993 David Koblas (koblas@netcom.com)
	and Copyright 1995, 1996 Torsten Martinsen (bullestock@dk-online.dk))
o There is a new mathematical model for splines. The new version uses X-splines
	which allows to mix interpolation and approximation points in a same
	curve. More precisely, it means that an X-spline curve is neither an
	interpolated spline nor an approximated one, it is BOTH (the behaviour
	of each point is controlled by one single parameter called "shape
	factor"). For additional information about X-splines, see:

	  "X-Splines: A Spline Model Designed for the End User"
	  by C. Blanc and C. Schlick, Proceedings of SIGGRAPH'95

  o the shape factor of each individual point can be modified interactively
    with a dialog box that is displayed when pressing the right button in
    the EDIT OBJECT mode.
  o the shape factor can also be modified in any of the EDIT modes, by
    holding down the CONTROL key while pressing the mouse buttons.
  o because the CONTROL modifier is used for the shape factor edition,
    the zoom rectangle is now obtained by pressing the SHIFT key AND the
    CONTROL key while dragging the rectangle.
  o new features have been added in the CONVERT mode. Any conversion between
    polylines, polygons, open splines and closed splines are now possible.

    *** Caveat: Because spline models of previous versions (quadratic B-splines
    and Bezier with hidden points) are no longer supported, curves that are
    present in version 3.1 and older files are automatically converted to
    X-splines. This translation is only an approximation process. It means
    that the converted curves are not exactly the same as the original ones.
    Though the translation usually provides almost identical curves, some
    hand-fitting may be needed in some pathological cases.

    The new spline features were written by Carole Blanc (blanc@labri.u-bordeaux.fr)
    and Christophe Schlick (schlick@labri.u-bordeaux.fr) starting from an initial
    implementation done by C. Feuille, S. Grosbois, L. Maziere and L. Minihot as
    a student practice (Universite Bordeaux, France).

o the file format (protocol) has changed (see Doc/FORMAT3.2 for details). This
	means you must also get transfig 3.2. Xfig will still read older Fig
	format files but will always write the new format.
o multiple page flag, paper size, transparent color (GIF export) and print/
	export magnification now stored in Fig file (new protocol format 3.2)
o export/print magnification now command-line argument (-magnification) and
	resource (Fig.Magnification)
o paper size now command-line argument (-paper_size) and resource
	(Fig.paper_size)
o multiple page flag now command-line argument (-multiple) and resource
	(Fig.Multiple) (-single is default)
o option of transparent color for GIF export (e.g. make background transparent)
o new colors in Fig-color.ad resource file from Joel D. Young
	(jdyoung@afit.af.mil).  If you want the old colors, copy Fig-color.old.ad
	to your app-defaults directory as "Fig-color".
o works with GrayScale, TrueColor, DirectColor, StaticColor and StaticGray
	visuals now.  Use "-visual <visualname>" command-line argument or 
	"Fig.visual: <visualname>".  Also, "-depth <depth>" (Fig.depth: <depth>)
	supported.
	thanks to help from Kevin Russell (krussell@dres.dnd.ca)
o "Delete All" button changed to "New" function - all objects are delete and
	the current filename is cleared.  Also, the file save and load shortcuts
	will force the file panel to popup if the current filename is empty.
	This will prevent a user from doing a "delete all" to create a new 
	figure and forgetting to change the filename when saving.
o new edit features when entering text on canvas:
	Left arrow key and Control-B moves cursor left
	Right arrow key and Control-F moves cursor right
	Home key and Control-A moves cursor to beginning of text
	End key and Control-E moves cursor to the end of text
	Delete key and Control-D delete the character to the right of the cursor
	Control-K deletes from the cursor to the end of the text
	Pan operations using the arrows and the Home key are disabled during
	text entry because they are used for positioning the text cursor now.
o "Open Compound" operation to temporarily go inside a compound object to edit
	individual components.  Can enter nested compounds. Close compound to 
	group objects back into compound.
	Written by Bill Taylor (bill@mainstream.com)
o xfig will now automatically unzip/uncompress Fig files with .Z, .z or .gz
	suffixes automatically.  It does not recompress/zip them when saving,
	though.
o -zoom (resource Fig.zoom) option to start xfig at any zoom value
o -startposnmode (resource Fig.startposnmode) option to start xfig with point
	positioning mode specified. Values can be 0 ("any") to 4 (1 inch/20mm).
o size of blank area (margin) around figure when exporting to bitmap-style
	formats (e.g. GIF, XPM etc.) is settable in export window now
o when zooming larger, spacing of dots in grid lines stays constant
o button to hide/show hidden directories (names that begin with ".") in file
	popup menus
o paper size selectable for printing and when exporting to PS/EPS:
	"Letter", "Legal", "Ledger", "Tabloid", "A", "B", "C", "D", "E", "A0",
	"A1", "A2", "A3", "A4" and "B5"
o in the past if an ellipse was scaled such that the radii become equal it was
	"converted" to a circle.  This "feature" has been removed.
o point objects (POLYLINES with only one point) now have thickness, as they
	should.  Additionally, if the cap style is rounded, they will be filled
	circles
o when exporting figure containing picture objects, xfig warns if the export
	filename is the same as any of the picture files
o note explaining how metric units are defined in xfig in the Doc/FORMAT3.1 file
o when updating objects with update button, they were drawn twice - now they are
	only drawn once
o when deleting xfig window (WM_DELETE_WINDOW), popup confirmation gives user
	the option to save figure
o README file updated to give credit for Example figures not done by Brian Smith
o default suffix for hpgl (ibmgl) export changed to "hpl" for PC users

BUGS FIXED

o smart links didn't work when the box being moved had line thickness > 1
o -exportLanguage ignores case now (e.g. GIF == gif)
o identical consecutive points in lines and "normal" splines are removed as file
	is read into xfig
o some thick arrowheads still protruded into the object they touched (in fig2dev
	too) - fix from Tobias Ringstrom
o resource for compose key database file is keyFile, not ComposeKeyDB (Fig.ad)
o color of labels for color numbers/names in color panel contrast their color
o edit panel allowed > 100% fill for black and white fill
o additional check for bad Bounding Box in imported EPS file
o when flipping objects vertically or horizontally, overlapping objects weren't
	redrawn
o format error in sprintf for temp filename in screen capture (%d should be %ld)
o some versions of imake don't like null parameters in SpecialObjectRule in
	Imakefile - changed to "NullParameter"
o "modified" flag wasn't being set when changing spline<->line or box<->arcbox,
	thus one could quit without saving without xfig confirming
	from Matthias Braun (browny@ise.fhg.de)
o when figure is read in from file, any arrowheads with width, height or
	thickness of 0 are given default values (were causing SIGFPE errors)
o colormap must be saved before jpeg_finish_decompress or
	jpeg_destroy_decompress are called in read_JPEG_file()
o when fore/background colors different from black/white respectively, the fill
	colors for black and white fill were incorrect
o when merging figure with no picture objects into figure with picture objects
	colors were unnecessarily remapped
o "rubberbanding" of object being drawn would continue after object was
	completed.  Also, double clicking on a directory name would cause
	segmentation fault.
	fixed by Stefan Proels (proels@fmi.uni-passau.de)
o Imakefile had error - $(PCXBUG) was incorrectly passed to f_readjpc.c
	instead of f_readeps.c where it was needed
o If the directory path in a file popup was changed by typing into the path
	window but carriage return wasn't pressed, rescan showed the correct
	directory but the path wasn't correct so no files were accessible.
o Redefined $(XPMINCDIR) to $(XPMINC) because some compilers have trouble with
	header search path with empty "-I"
o string allocation errors in string widgets in popup edit panels
o no return code for successful screen capture which would result in failure
	randomly
o picture objects scaled (enlarged) correctly in metric mode so they print 1:1
o incorrect values for white colormap entry when writing jpeg file on
	monochrome display
o Some people have older X11 include files that don't have <unistd.h> included.
	fig.h explicitely includes that now for the SEEK_END identifier
o Not enough space for number strings in rulers (SEG fault)
o circle grab points moved even if no changes made in popup edit of circle or
	ellipse object
o after attempt to do a horiz/vert move point of a circle was disallowed,
	further move points were disabled until edit mode switched
o if both points of "circle-by-diameter" have same y value it thought that the
	edge is the center when you try to use "box scale"
o colormap from jpeg file was referenced after memory was freed
o #include <jpeglib.h> changed to #include "jpeglib.h" to ensure corrrect path
	used to find header file
o problems on Linux with gcc locating old jpeg library even when JPEBLIGDIR
	pointed to local version
o buf too short in set_mixed_names
o line2 too short in button struct
o file not closed after writing JPEG file
o pen color for picture objects disabled for all except XBM (bitmap) in popup
	edit
o confusion with -DNOSTRSTR, NOSTRSTR and HAVE_NO_STRSTR cleaned up. See README.
o possible error in rulers with sprintf %f called with integer expression
o cleaned up add/delete user defined colors - no requirement to click on
	colorcell after "Add Color" to set color sliders
o added condition in Imakefile that f_wrjpg.c depends on jconfig.h (jpeg library)
o changed #include <jpeglib.h> to #include "jpeglib.h" because of search rules
o Version 1.0 of Xaw3d used resources topShadow and bottomShadow for colors of
	those resources.  Version 1.1 uses topShadowPixel and bottomShadowPixel.
	I have included both names in the Fig.ad app-defaults file for
	compatibility.
o removed extraneous comma (,) in length and distance messages when
	drawing/moving objects
o cleaned up many type mismatch warnings for bitmap data
o bug in skip_comment() which prevented some machines from seeing the end of
	file, giving erroneous "Incorrect format" error
o typos in xfig.man in resources StartGridMode, StartPosnMode, StartLineWidth,
	StartFillStyle and StartTextStep (had lowercase 's')
o pcx file was closed twice
o if there is an error when writing screen capture to a file, the popup error
	message window shows the error
o Examples/logo.fig had squished logo eps file

=============================================================================
Version 3.1
=============================================================================

Patchlevel 4b (May, 20, 1996)

BUGS FIXED

o arrowheads caused DOMAIN error for asin on very small arcs
o constraint loop error when starting xfig with button panel on right side fixed
o Some compilers optimized away the dummy functions in f_readxpm.c and f_wrxpm.c
	because they were static but never referenced.  These dummy functions
	are needed when the XPM code is not used, for those same compilers that
	don't like empty .o files.  The "static" has been removed.
o BoundingBox handled better with importing EPS figures
	from Yves ? <root@marin.sevy.fr; however, mail to this address bounced>
o meta characters in file names (e.g. "&", "|", etc.) weren't properly escaped
	when passed to fig2dev or when printing
o changing directories in the image browser broke file/export directory widgets
o user-defined fill colors above 63 were being limited to 63 when reading in
	Fig file
o bug in zoom macros resulted in some objects being shifted when zooming
o segfault when importing jpeg picture with grayscale colormap fixed
o when moving text that is currently off the positioning grid, and positioning
	grid is turned on, text is correctly placed on the grid now
o changing between portrait and landscape mode keeps previous canvas size
o limits.h included now for i386 and SVR4 machines
o when switching between inches and metric mode, the figure on the canvas is 
	scaled appropriately, so that (e.g.) a 1 inch line becomes a 2.54 cm
	line instead of 2.666 cm as it use to.
	from Henning Spruth (hns@regent.e-technik.tu-muenchen.de)
o changed "METHODDEF" to "static" for f_readjpg variables because the definition
	of METHODDEF changed in jpeg-6a
o xfig incorrectly interpreted the WM_SAVE_YOURSELF signal from window managers
	for now, this signal is ignored until I have time to "do the right
	thing", which is to checkpoint xfig so it may be restarted later in
	exactly the same state (figure and panel settings etc) if the user
	desires to do so.

-----------------------------------------------------------------------------
Patchlevel 4a (Aug, 24, 1995)

BUG FIXED

o incorrect values for white colormap entry when writing jpeg file on
	monochrome display

-----------------------------------------------------------------------------
Patchlevel 4 (Aug, 16, 1995)

NOTE 1: The Display PostScript code is not supported anymore until some kind
	user can debug it for me, as I have no access to a server with DPS
	extensions.  Use ghostscript for rendering your EPS files.  It gives
	a color image on the xfig canvas now anyway.

NOTE 2: Because Unisys has stated that they will not charge royalties for the
	use of the LZW compression algorithm in *FREE* programs, xfig will
	continue to support importing and exporting of GIF images.
	However, be aware that if you sell xfig, for example as part of a CD-ROM
	package with freeware, you may be liable for paying royalties to Unisys.
	The authors of xfig and the Lawrence Berkeley National Laboratory cannot
	be held responsible in any case.

NOTE 3: Because of the patent/licensing issue with Unisys and the LZW compression
	algorithm used in GIF files, the author of ghostscript has decided to
	remove GIF support from that program.
	xfig will now use PCX output from ghostscript when importing EPS files.
	This means that you must compile ghostscript with the pcx256 and pbmraw
	drivers.
	Additionally, there is a bug in the pcx driver in Aladdin Ghostscript
	versions prior to 3.32, which writes an incorrect pcx file for images
	with odd width (not even).  There is a compile-time flag set (the
	default) to make xfig add one pixel to the width of an odd-width image
	when it reads in the pcx output from Ghostscript.
	If you have Aladdin Ghostscript 3.32 or newer (which wasn't released
	as of this writing) you may comment out that flag and your images will
	have the proper width.  However, one pixel extra in width shouldn't
	matter for most imported eps files.

NOTE 4: The -textoutline (resource textoutline) option has been moved into the 
	-debug option.  This makes xfig draw a red box around text objects for
	debugging purposes.

NEW FEATURES:

o JPEG (JFIF) images can be imported and exported - see Examples/pictures.fig
	Unless you have an image (picture object) in your figure, you may not
	gain very much by exporting in JPEG over GIF because of the nature of
	compression used in both methods.  GIF is usually better for line
	drawings or drawings with large blocks of continuous color (e.g. filled
	polygons).  JPEG is usually better for compressing images.
	The quality factor for exporting JPEG is fixed at 75.  This seems to be
	fine for figures containing only solid objects (no images) and adequate
	for figures containing imported images (GIF, JPEG, etc.).
o New features in the Picture Object edit popup:
	1) Capture a screen image to a GIF file to use for importing.
	2) Call an image editor (e.g. xv) to edit an imported image. New
	   resource for the editor: "Fig.image_editor: xv" (default)
	3) Popup a file browser to look for images to import.
	all from Jim Daley (jdaley@cix.compulink.co.uk)
o the points of arrow heads don't protrude past the endpoints of the object
o when drawing polyline/polygon or spline you can delete newly created points
	by pressing shift-mouse button 1
o when saving figure, original is first renamed to file.bak to make backup file
o smartlinks improved - lines touching boxes inside compound object will be
	moved when compound is moved with smart links mode on
	From Ian Brown
o -help option to print all command-line options to xfig
o can now change boxes to arc-boxes and vice versa with same button that
	converts lines <-> splines.
o label in fill style panel added to separate shaded fill from pattern fill
	(if the pen and fill colors are both black or white it was impossible
	to distinguish the patterns from the 100% shade fill)
o when adding a new user-defined color, it is automatically selected for
	modification without having to click on the cell.
o point positioning now has five resolutions: arbitrary, 1/16" (1mm),
	1/4" (5mm), 1/2" (10mm) and 1" (20mm)
o increased resolution of dimensions in message window when drawing/moving
	objects from 2 to 4 decimal places
o new meta sequence "%f" in print parameters is replaced with current filename
	for printing. Can be used for job name to printer.
	(e.g. lpr ... -J %f ...)
o version/patchlevel added to error handler messages to identify version of xfig
o new export option for MetaFont language
o new resources for ruler and unit box fonts: *topruler.font, *sideruler.font
	and *unitbox.font.  See Fig.ad.
o new resource (Fig.rulerthick:) and command-line arg (-rulerthick) to set
	thickness of rulers (height of top ruler and width of side ruler)
o note about patch for HP compilers in README file (see "Possible problems...")
o on abort, xfig does a cd to the original directory where it was started so
	that any core dump will be in the original directory
o strncasecmp and strcasecmp routines provided for those systems that don't have
	them.  See the Imakefile . From Fred Appelman (Fred.Appelman@cv.ruu.nl)

BUG FIXES:

o fig.h includes sys/types.h for BSD and Mips systems and excludes errno,
	sys_nerr and sys_errlist for BSD
	from Kurt J. Lidl (lidl@va.pubnix.com)
o error in path for xpm.h in resources.h
o reversed #elif conditions in fig.h for linux/osf defs of random() and srandom()
o text size problem when reading file with text when zoom != 1.0 fixed
o deleted user colors still showed up in color menu in "edit object" panel
o when rotating or flipping an object, the new position wasn't kept on the
	point positioning grid
o selecting drawing mode using keyboard accelerators now updates mouse
	indicator window
o undo of multiple copy (array place) now undoes all objects
o undo of "figure load" properly sets "current filename" in File popup and
	"default filename" in Export popup back to original values
o undo of "figure load" does not set "figure modified" flag now
o changing the figure orientation to/from Landscape/Portrait is considered a
	figure modification for quitting/saving
o GIF export was not available if XPM not installed - rearranged order
o misplaced fclose() in f_readeps.c
o misdeclared function close_picfile() in f_readeps.c
o infinite loop when copying a line after scaling a compound using the move
	point mode
o bitmap image of Latex "Italic" font was mis-named "Italics"
o no more hard-wired setting of background for mode and indicator panels
	see Fig-color for more details
o font size for text objects adjusted if < 4 points or > 1000 when reading file
o update settings from object wasn't setting PostScript vs LaTeX flag when Font
	update indicator was enabled
o more checking done in popup edit panel for illegal line thickness or depth
o flip or rotate anchor/center point crosshair turned off when selecting new
	drawing mode
o seg fault in import/edit of picture object due to filename string corruption
o segfault sometimes on file load - gcc sometimes produces code which segfaults
	when doing ungetc on const string. Constant string copied for sscanf
o bug in computing the center of an arc when scaling
o smarter redrawing of objects in correct depth order when creating or modifying
	any object
o changed bestd = ~(((int) 1)<<31); to bestd = INT_MAX in f_neuclrtab.c due to

o if -textoutline was specified, boxes appeared around text when exporting to
	bitmap-type format (e.g. GIF, XBM, etc)
o if the file message window popped up before canvas translations were installed
	a warning about the PasteCanv action not being found resulted.  This was
	fixed by narrowing the specification for the translation in the
	app-defaults file.
o bounding box for text objects was incorrect when loading file with zoom != 1.0
o bounding box for ellipses was incorrect with thick lines
o bug in handling text objects with \ at end
	patch from Andrew McParland (akm@rd.bbc.co.uk)
o mis-named character "acute" removed from the multi-key sequence list in man
	pages
o LaTeX font "Modern" changed to correct name "Sans Serif"
	new menu bitmap from Volker Kuhlmann  (kuhlmav@elec.canterbury.ac.nz)
o bounds calculation of objects didn't take line thickness into account
	correctly
o drawing very small arcs (e.g. when zoom is small) resulted in strange lines
	being drawn
o importing XPM images with undefined colors resulted in an X error.  Now xfig
	uses white for null color entries.
o problems with XFree86-3.1.  Get XFree86-3.1.1.
o some picture objects without filenames would be saved incorrectly and
	couldn't be re-read
o extraneous error message about inaccessible file when it contains bad Fig
	object
o bug in bounding box calculation created compound objects off by one unit
o added #include <sys/types.h> for ultrix file stat structure
o bug in scanning 8-bit character followed by a number in text object
	(e.g. \24355 should be the British Pound Sterling character followed
	by 55, not character (octal) 24355)
o in older Fig files (2.1) text at 90 degree angle was slightly jagged due to
	rounding error
o xfig doesn't coredump when delete window operation is done on xfig window or

	steps to not allow arrowheads for those
o undo of delete arrowhead created arrowhead with current line thickness etc.
	instead of restoring original
o removed extraneous comma (,) from lp command for SYSV/SVR4 systems.
o changed the "-oPS" command-line option (used for SYSV systems) to "-T PS"
	in the Fid.ad app-defaults file.
o typo in FORMAT3.1 file - line and arrowhead thicknesses units are 1/80 inch,
	not Fig units.  Also, dash/dotted size/spacing are in 1/80 inch units.
o some compilers don't like empty .c files (e.g. when XPM is not compiled in)
	static dum_function() placed in f_readxpm.c and f_wrxpm.c for that case
o bug in #include for xpm.h - X11/xpm.h was appended to XPMINCDIR - removed X11/
o added #ifdef ultrix to include <sys/types.h> which is needed for <sys/stat.h>
o black and white colors in colorpanel were set to fore/background colors
	instead of black and white (problem when -bg and/or -fg used)
	from Matthias Braun (browny@ise.fhg.de)

	was behind by one point positioning unit until new point was established
-----------------------------------------------------------------------------
Patchlevel 3 (Jan, 24, 1995)

BUG FIXES:

o when using the 3D Athena widgets, user defined color buttons in popup color
	panel were allocating three colors per user color - fix to app-default
	file fixed that (3D widget set was trying to make shadows)
o EPS objects were too small when "Use orig. size" used in edit panel
o hexadecimal color names not parsed correctly for xpm images
o moved include of <stdio.h> and some others above <X11/Xlib.h> for gcc
	warnings about NULL being redefined
o LaTeX text with special flag had wrong style (Roman became Italic etc.)
o cap style implicitly set to ROUND for ellipses and closed splines with
	dotted lines
o some cleanup of pointer/data type casts
	from Randy MacLeod
o incorrect parameter for ibmgl export mode - incorrectly used -L for landscape
o more #ifndef/#endif surrounding random, srandom and frandom in fig.h
o removed the -oPS command-line option for SYSV systems because it is printer
	dependent.  Use the "Fig*job_params*string: -oPS" resource.
o can now dismiss message window while edit panel is up
o command string for printing file too short for some cases - increased

-----------------------------------------------------------------------------
Patchlevel 2 (Jan, 13, 1995)

BUG FIXES:

o ISO8859 restriction on font searching was inadvertantly removed - added back
o hexadecimal color names not parsed correctly xfig standard colors. This was
	causing xfig to switch to monochrome mode after complaining that it
	couldn't allocate the standard colors.
o definition for XCOMM in Imakefile for those running R4
o fixed problem with popup message panel having wrong colors when xfig switches
	to a private colormap
o objects with dotted lines didn't show until an object with dashed line was
	first created
o moved #include of X11/Intrinsic.h to top of fig.h file so
	XtSpecificationRelease would be defined when needed
o comment for patchlevel 1 about command-line option -dontswitchcmap misspelled
o new label in print panel - "Print to PostScript Printer" makes it obvious
	that the only printer type available is PostScript

-----------------------------------------------------------------------------
Patchlevel 1 (Jan, 11, 1995)

BUG FIXES:

o couldn't read eps files that didn't have showpage command
o segfault when non existent eps or other image file is referenced in a figure
o command-line option -dontswitchcmap (resource Fig.Dont_switch_cmap) fixed
o export and file load/merge offsets units (inches, cm, etc) not correctly
	set when -metric option used
o seg fault when converting line to spline because cap_style wasn't initialized
o when converting spline to line, cap_style was set to current cap_style
	instead of style of line being converted

-----------------------------------------------------------------------------
Patchlevel 0 (Jan, 9, 1995)

BUG FIXES:

o NOTE:	An error in version 3.0.0 incorrectly positioned objects on the canvas
	when reading older fig files.  New objects entered with 3.0 are
	correctly positioned.  A warning will popup when you load a version 3.0
	file with version 3.1 that says you might need to offset your figure by
	14 fig units in X and Y when you load it.  This is done by setting the
	X and Y offset in the popup File panel.
	I apologize for the inconvenience.

*****	This is also why the file version number has changed.

o conditionals and macros added for for machines with different random number
	generators
o segfault in show_pen_color and show_fill_color under certain conditions when
	switching colors
o error in x/y load/merge offset when reading pre 3.0 files
o bug in drawing large (6 inches diameter or larger) circles or ellipses with
	dashed or dotted lines and angle of 0 degrees.
o extra line was drawn to center of ellipse or circle when dashed or dotted
	lines used and angle of 0 degrees.
o bug in f_read.c which caused FPE errors when reading incomplete/incorrect
	Fig file
o declaration of count_lines_correctly() inconsistent in f_read.c
o incorrect cast using malloc in f_readxpm.c()
o setcenter, setcenter_x and setcenter_y should be extern in e_flip.c
o setanchor, setanchor_x and setanchor_y should be extern in e_rotate.c
o text following #endif non-ANSI in main.c
o error in source file names in Imakefile - had f_wrgif.o instead of f_wrgif.c
o error in freeing NULL font struct when quitting xfig (in u_free.c)
o renamed basename() to basname() to avoid conflict with Linux libc function
o error in LaTeX font numbering in Doc/FORMATx.x files
o major errors in reading version 1.3 files
o overriding translations in turn_on left black outlines around buttons in
	mode panel when new mode button pressed
o some servers drew black background in indicator panel buttons - caused by
	fill mode being "tiled" for buttons other than the fill style button
o images (GIF, XPM etc) weren't always recolored correctly when using popup
	edit panel on picture object
o DPS fixes for Solaris 2.3
	from Pete A. Zaitcev (zaitcev@lab.ipmce.su)

=============================================================================
Version 3.0
=============================================================================

Patchlevel 0 (Dec 22, 1994)

NEW FEATURES:

o changes to the file format (protocol).  See Doc/FORMAT3.0 for details.  This
	means you must also get transfig 3.0.  Xfig will still read older Fig
	format files but will always write the new format.

 These are the new features related to the new file format:
-----------------------------------------------------------------------------
   o resolution is increased from 80 ppi to 1200 ppi.  This decreases jaggies.
	A side effect is that xfig can now read fig files of any resolution,
	although it converts the file to 1200ppi internally, and saves it in
	that resolution.
	from Ross Martin (martin@trcsun3.eas.asu.edu)
   o Portrait/Landscape, Print Justification (center or flush left) and Metric/
	Inches indicators saved with figure file now - xfig automatically
	switches to correct mode when reading file
   o separate pen and fill colors for all objects except text.
   o there are now 32 "standard" colors - new ones are: gold, three shades each
	of blue, green, cyan, red, magenta, brown and pink.
   o in addition, there are now user-definable colors which may be defined by
	using RGB (Red, Green, Blue) or HSV (Hue, Saturation, Value) slider bars
	or by hexadecimal values. These are stored in the figure file as pseudo-
	objects of type 0 which define the rgb values in hexadecimal.  The color
	numbers range from 32 to 543.
   o more fill options - colors transition from black to full saturation
	(shades) and on to full white (tints, i.e. pastels).
	Or you can use one of 16 fill patterns - diagonal lines, bricks,
	shingles, crosshatch etc.
   o two arc styles: open (original) and pie-wedge (closed)
   o three line-join styles: miter (default style), round and bevel (see
	PostScript or Xlib reference for description)
   o three line-cap styles: butt (default style), round and projecting (see
	PostScript or Xlib reference for description)
   o three new arrowhead types (both hollow and solid)
	and the tips of the arrowheads are now pointed, as they should be
-----------------------------------------------------------------------------
Features which are independent of the new file format:

o EPS objects have been changed to "picture objects" to include GIF images,
	X11 bitmap images and the XPM3 (color pixmaps) besides Encapsulated
	PostScript.  Compressed (.Z) and gzipped (.z or .gz) files are also
	handled.  Future versions of xfig may include TIFF, etc.  X11 bitmap
	picture objects use the pen color component.  The popup edit panel
	shows the image type, size and number of colors used, if applicable.
	See the Examples/pictures.fig for examples of XPM, XBM and GIF.
	You must have version 3.4c or newer of the XPM library.  This is
	available from ftp.x.org in /contrib/libraries.

	GIF input code from David Koblas' giftoppm code from the pbmplus
	package.

	A Floyd-Steinberg dithering is applied to color images for monochrome
	displays.

	For EPS files, if Ghostscript is used to generate the preview, an 8-bit
	color preview is generated if xfig is running on an color display.
	The command-line option -dSAFER is used when calling ghostscript which
	prevents any files being written by the postscript code.

	The color quantization algorithm to minimize the number of colors
	needed for the color images uses a neural network scheme written by
	Anthony Dekker (dekker@ACM.org).  
	[NEUQUANT Neural-Net quantization algorithm by Anthony Dekker, 1994.
	See "Kohonen neural networks for optimal colour quantization"
	in "Network: Computation in Neural Systems" Vol. 5 (1994) pp 351-367.
	for a discussion of the algorithm.]

o support for Input Tablet - see Imakefile
	Greg LaCoste (greg@seismo.do.usbr.gov)
o when moving an object on the canvas the straight-line (sqrt(x^2 + y^2))
	distance from the original position is reported in the message panel
	along with the X and Y distances.
	from Uwe Bonnes (bon@lte.e-technik.uni-erlangen.de)
o rotate or flip objects around a chosen anchor point - see FLIP and ROTATE
	sections in the man pages.
	from Uwe Bonnes (bon@lte.e-technik.uni-erlangen.de)
o make multiple copies of object as you rotate or copy it - see COPY section in
	the man pages
	from Uwe Bonnes (bon@lte.e-technik.uni-erlangen.de)
o new command panel button to switch canvas between Portrait and Landscape mode
o new option in file load/merge panel to load/merge figure with offset on canvas
o new option to export file with offset on page in inches or cm
o OE and oe characters possible now; though not visible on the canvas because
	they don't exist in the X11 fonts they will print in PostScript
	from Serge Lacourte (lacourte@bikini.imag.fr)
o starting textstep, fillstyle, linewidth and gridmode can all be specified
	with command-line args or resources now (see man pages)
	from Serge Lacourte (lacourte@bikini.imag.fr)
o larger grid (1 inch or 20 mm)
o when zooming very small, number of grid lines are reduced to avoid clutter
o more keys available for multi-key sequence: Alt_L, Alt_R and Escape besided
	the usual Meta key
	from Serge Lacourte (lacourte@bikini.imag.fr)
o in update mode, the control panel doesn't scroll with the indicator buttons
	but stays on the left side all the time
o rulers are a little smarter - fewer labels and ticks when zoom scale is small,
	0.5 inch marks for inches scale when large enough
o minor changes to names of some widgets - "xfig_" prefix removed from those
	having it
o can use "box-scale" on ellipses and circles now besides "scale about center"
o new alignment options - Distribute objects evenly horizontally, vertically
	or both, spacing either their edges or centers evenly, or abutting
	their edges
	from Matthew Leditschke (mcl@eikona.eng.monash.edu.au)
o keyboard icon appears in mousefun window when text entry is required
	works during canvas text entry and in ASCII widgets in popups
o carriage return in any ASCII widget in edit popup applies changes
o zoom in and zoom out accelerators (Z (zoomin) and z (zoomout) defaults)
o popup font menu is now two entries wide to reduce overall height
o panning is proportional to zoom factor, i.e. pan step is 1/2 inch in canvas
	units, not drawing units
	from Anthony Smith
o holding down the Shift key while panning pans 5x as far
o fill style indicator shows current color now
o two new Example files: illusion.fig and recycle.fig
	from Vivek Khera (khera@cs.duke.edu)
o four new clip-art files (Examples directory): clp_bldgs.fig, clp_network.fig,
	clp_computer.fig and clipart.fig
	from William J. Chimiak (chim@relito.medeng.wfu.edu)
o new export languages - GIF and X11 Pixmap (XPM, color X pixmaps) output
	- must have the XPM3 package for XPM output.
	XPM3 code from Karel van Houten (K.H.C.vanHouten@research.ptt.nl)
	GIF code from E. Chernyaev (chernaev@mx.decnet.ihep.su)
o can handle eps files with %%BoundingBox: (atend)
	from Paul Hodgkinson (hodgkin@physchem.ox.ac.uk)
o no need for the -DNOSTRTOL flag anymore if your system doesn't have strtol()
o export magnification factor added for X11 bitmap/pixmap output
o MAXNUMPTS (the maximum number of points displayed for large objects) may be
	specified in the Imakefile with -DMAXNUMPTS=xxxx, if desired

BUG FIXES:

o first/opposite corner designation for box objects was reversed in popup edit
o line count correct when reporting any errors reading figure file
	from Andreas Bagge (Andreas_Bagge@h2.maus.de)
o when scaling box object, size of box now shown with first click when using
	middle button
o more sanity checks on starting values (e.g. -startfillstyle < 0 etc)
o changes in dot/dash spacing were sometimes delayed in effect.  Fixed.
o if printer name came from env variable, it didn't show up in print panel until
	first figure was printed
o smarter redraw of underlying objects when updating or rotating objects or
	moving, adding or deleting points of an object
o metric scale is now correct size when printing
	from Hans Werner Strube (strube@swing.physik3.gwdg.de)
o temporary file for importing EPS objects wasn't honoring XFIGTMPDIR
o text angle was written with only 5 decimal places - causes rounding errors
o after adding/deleting a point from a poly object, copying a compound object
	would cause xfig to hang (loop in linked list)
o grid wasn't reset when changing to/from Imperial/Metric scale
o "Ruler units" message was incorrect when changing to/from Imperial/Metric
o file_msg() routine now uses varargs
	old method was causing crashes to occur on a 64 bit machine
o toggle of update masks wasn't using correct variable
o when drawing a dotted line with only two points which are coincident, some
	servers die and others give BadLength error.  A call to draw a point
	is substituted in this case.
o bug in changing directory using ".." in text panel for "Curent Directory" in
	file and export popups
o in monochrome mode, popup color choice panel black/white reversed from
	indicator button for blue-yellow
o first section of man pages didn't mention IBM-GL language in reference to
	fig2dev
o filled objects didn't show the fill pattern in monochrome mode
o seg fault when xfig used default font when desired font could not be found
o fixed some memory hog problems with accelerators
o some typos in the class names of bold/normal/button fonts in man pages
o double clicking on a filename to load it sometimes resulted in garbage or
	blank filename in file name panel.
o remnants of #ifndef NO_SIBGUS (note typo) fixed.  NOW there is no need for
	#define NO_SIGBUS if your system doesn't have SIGBUS.  Automatic now.
o typo in fig.h check for #ifdef(SYS) instead #ifdef(SYSV).
o added check for SCO3.2r4 which needs stdlib.h for atof() and getenv()
o switching between LaTeX and PostScript fonts while entering text object
	caused illegal font to be created in text object
o GC's tr_gc, tr_xor_gc, tr_erase_gc, sr_gc, sr_xor_gc and tr_erase_gc declared
	in resources.c and in w_rulers.c
o cur_cursor set to arrow_cursor before arrow_cursor was created
o experimental color definitions in resources in main.c clobbered variables
	because array wasn't large enough.
o false query about overwriting existing fig file fixed
o shifted keyboard accelerators work with caps lock besides shift key
o text bounds fixed
o smarter text locator when moving rotated text
o missing "return 1" in bitmapDPS procedure (Display PostScript machines)
o type mismatch in w_rottext.c ("return NULL" changed to "return 0") in
	XRotPaintAlignedString()
o bug in memory allocation for font name when desired font doesn't exist
o increased memory allocation for large, rotated ellipses

=============================================================================
Version 2.1
=============================================================================

Patchlevel 8 (Oct 1, 1993)

NEW FEATURES:

o minimum movement for mountain/manhatten mode reduced from 7 pixels to 2
o lengths/radii of objects now displayed on first click in move point mode, not
	just when actually moving the points
o -DOPENWIN no longer necessary - xfig automatically first uses OpenWindows
	scalable fonts (e.g. times-roman-33) if they are available, X11R5
	scalable fonts next if they are available or non-scaling fonts if
	neither of the above is available.
o maximum radius of arc-boxes increased from 30 to 100 pixels
o icon now shows current filename (without full path)
o Control-L does Redraw when not in text input mode (same as Meta-R)
o popup query to shift whole figure when reading in figure file if any objects
	have negative coordinates
o mouse function window shows pan/zoom operations when control key is pressed
o popup query when exporting figure if figure has not been saved (note: this
	is not necessary for exporting current figure but is a warning to
	the user that the figure hasn't been saved yet)
o BSD-style printing on SYSV machines (like SGI) allowed by setting -DBSDLPR
	in Imakefile/Makefile
	from Dave Goldberg (dsg@blackbird.mitre.org)
o on-screen rotation of text at any angle
	xfig now uses xvertext 5.0 from Alan Richardson which allows rotation
	at any angle. The whole font is not loaded anymore, and strings are
	cached, which speeds up the interactive input of text.
o man pages no longer use .TS (table) commands for those systems whose roff
	doesn't support tables.  Also formatting cleaned up and typos fixed.
	From David W. Sanderson (dws@ssec.wisc.edu)
o double click on filename in File menu will automatically load figure
o double click on filename in Export menu will automatically export figure
o some more information about text objects has been added to the Doc/FORMAT2.1
	file - specificly about the font and font_flags fields
o keyboard accelerators for drawing/editing mode panel.  See Fig.ad for details
	From Tim MacKenzie (tym@dibbler.cs.monash.edu.au)
o Example figure which contains building blocks for making flowcharts - called
	flowchart.fig in the Examples directory (replaces old flowchart.fig)
	from Tim P. Starrin (noid@cyborg.larc.nasa.gov)
o The default is now for xfig to use X11R5 scalable fonts unless the server
	doesn't support them.  The user may still disable them with -noscalable
	or the resource "Fig*scalablefonts: false".
o new button panel in the indicator panel to set/clear or toggle update flags to
	make it easier to control which object attributes are affected by update
o new command-line paramter: -but_per_row (resource But_per_row) specifies the
	number of buttons wide the mode panel should be.  This is useful in
	conjunction with -pheight for small screens to reduce the canvas area.
o no need to add -DNO_SIGBUS to Imakefile for systems without SIGBUS anymore.
	This this is automatic now.

BUG FIXES:

o changing a filled object to unfilled now draws background correctly
o cleaned up inconsistencies with fill colors in monochrome mode
o GC's were being freed twice if window quit was executed (window manager)
o exporting figure to X11 bitmap only exported visible part of canvas
o current directory wasn't set in export popup unless file menu had been popped
	up previously
o units box didn't change from "in" to "cm" or vice versa when changing from
	Imperial to/from Metric
o editing text with popup edit at zoomscale != 1 shows correct text size now
o undo of text delete at another zoomscale shows correct text size now
o colons (:) removed from widget names (difficult to set resources with colons)
o conditional definition of index = strchr (or strchr = index) for those systems
	which already have them defined
o workaround for linux bug where certain 8-bit characters are not read properly
	by sscanf()
	from Alain Lucien Knaff (knaff@mururoa.imag.fr)
o height of cursor for text input closer to actual text height (was "descent+
	ascent" tall, now is "ascent" tall)
o <Meta>L (LoadFile function) didn't query if current figure was modified before
	re-loading file
o if normalFont can't be loaded, "fixed" font is tried - if that fails xfig
	quits with error message
o 8-bit character did not appear on canvas
o semicolon missing from "for" statement in main.c
o caused core dump if the environment variable PRINTER was not set and the
	Fig*printer*string was not set
o -startfontsize parameter wasn't being honored
o quit() function was being called with too few parameters.  This kills xfig
	on OpenWindows servers.
	From David Partain (dlp@ida.liu.se)
o fixed bug with freeing two identical GC's (caused coredump when quitting on
	certain machines)
o fixed bug inadvertently introduced in 2.1.7 which caused some arcs to be drawn
	as circles
o scaling of arc inside compound no longer produces co-linear points
o messages didn't appear in the message panel when filename panel wasn't
	large enough
o parameter missing from call to curve() which made strange half-ellipse for box
	curve radius indicator. Caused massive problems for OpenWindows servers.
o moved two accelerators (SaveFile and LoadFile) from top-level to the File
	widget heirarchy (this was causing OpenWindows servers to eat memory)
o work around for bug in OpenWindows 2.0 with bitmaps in widgets (caused
	BadMatch error when popping up the print panel)
o duplicate .TP in xfig.man caused nroff to throw away the text following the
	"Dismiss" description in the print section
o emptyname() dereferenced null pointer if printer name was NULL
o malloc didn't alloc enough space for fontname + null in w_drawprim.c
o text outline box was sometimes drawn incorrectly
o Renamed ICONFIGFILES (already used by X11 config) to ICONXFIGFILES and defined
	it in Imakefile (it was referenced but undefined)

------------------------------------------------------------------------------
Patchlevel 7 (May 3, 1993)

NEW FEATURES:

o Vertical and upside-down text - text with angles of 90, 180 and 270 degrees
	supported. Text between those angles will be drawn with the next
	higher angle (e.g. 130 degree text will be drawn at 180 degrees).
	from Alan Richardson (mppa3@uk.ac.sussex.syma)
o message panel uses asciiTextWidget so one may select text from it
o does not ask if it is OK to write an existing file during save if it is the
	current figure file that is being saved.  Same for export.
o accelerators to Save or Load file without popping up file menu
	(default: Meta-S to Save and Meta-L to Load)
o PRINTER environment variable is used if no resource is set for
	Fig*printer*string
o if an ellipse is scaled such that the radii become equal it is "converted"
	to a circle
o ablity to change to/from imperial and metric with popup menu by hitting
	mouse button 3 in the units box (where rulers meet)
	from Paul King (king@cs.uq.oz.au)
o new command-line parameters -userscale (resource userscale) and -userunit
	(resource userunit) which are used in the on-screen messages which
	show the current length/diameter etc.  This provides a simple way of
	doing scale drawings, e.g. 0.25 inch = 1 ft (userscale=0.25,
	userunit="ft") or 1 cm = 1 m (userscale=1, userunit="m").  These may
	be changed via the popup menu by hitting mouse button 3 in the units
	box (where rulers meet)
o new indicator button allows text flags to be viewed/set

BUG FIXES:

o typo in man pages with menu item "Textyl \special commands" in export menu
o action changed from "cancel" to "dismiss" for print menu accelerator
o bug in Intrinsics? on Sun Monochrome prevented side ruler from scrolling

	(in 2.1.4, the upper-left corner was placed at 10,10)
o changed "char" to "unsigned char" for initialization of bitmaps by compilers
	from Teus Hagen (teus@oce.nl)

	and you will see the full Postscript object instead of preview bitmap
	when you include EPS objects.
	!!! WARNING: this has only been tested on IBM's AIX 3.2 (X11R4) on
	an RS/6000 !!!

	UPDATE text object operation when switching from LaTeX to PostScript
	or vice versa.
o the textstep value may now be entered in floating point in the popup menu
o the eps-bitmap icon was renamed to eps-object because it can be any

	that will be displayed.  Several filenames/program variables
	were also changed to reflect this.
o there is now a more general glue mechanism for compounding objects
o text pasting into canvas now possible with F18 function key or any translation

o both ps and eps modes now supported in export menu.
o new directory browsing facilities integrated with File and Export popups.
	Allows selection of file by clicking on the filename.  Has mask to list
	only those files of interest.  See the man pages for further details.

	text as the default
o bug fixed where number of objects count in file popup was sometimes clipped
------------------------------------------------------------------------------

Patchlevel 1 (Oct 1991)

o xfig now reads text size, height and length as floats and rounds to ints
	this is done because certain programs generate floats for these
o compound object was rounded to next larger grid even if objects inside were
	already on the grid
o Examples/logo.fig included Logo.eps instead of logo.eps
o cancellation of line drawing left single dot on screen
o filename in File popup menu didn't get set until first popup - file save

o bug fixed which caused incorrect mode after cancelling draw (int)spline
o bug fixed which caused incorrect minimum number of points for (int)spline
o bug fixed which caused erroneous large values to occur after box scale of
	0-width or 0-height objects.  You can no longer box scale such objects
------------------------------------------------------------------------------

Patchlevel 0 (Sep 1991)
Changes to Version 2.0 Patchlevel 10:

Implemented by Paul King (king@cs.uq.oz.au) and
Brian Smith (bvsmith.lbl.gov) with help from
Micah Beck (beck@cs.cornell.edu) and
Brian Boyter (pyrdc!bimbo!boyter@uunet.UU.NET) (EPS code).

USER INTERFACE
--------------

o The buttons are now grouped into three panels:

    COMMAND panel:
        Quit, Delete all, Undo, Redraw, Paste, File popup, Export popup and
		Print popup buttons.  See man pages for details.
		(see "Drawing Modes", below for description of Cut)
    MODE panel:
	Allow the user to select the current drawing or editing mode.
    INDICATOR panel:
	By default shows indicator buttons relevant to the current mode.
	Each indicator button displays current setting of some quantity
	(e.g. line width, area-fill) and allows it to be changed:
        left button gives popup menu to select setting,
        middle/right buttons provide a shortcut to inc/decrement settings.

o Pan figure by using left/middle/right button in the rulers in addition to
	the previously supported arrow keys.  Also a pan to origin operation
	is available by clicking in the units window (or using HOME key).
o May now print figure that hasn't been saved (i.e. print what is on the
	canvas, not the file)
o Zoom up or down with zoom button.
o Mouse function window shows function of active buttons
o New resources/command-line switches which affect the user interface:
	-showallbuttons		(show all indicator buttons all the time)
	-internalBW n		(use lines of width n between buttons/panels)

DRAWING MODES
-------------

o Regular polygon drawing button - select number of sized from bottom panel.
        Object created is normal xfig polygon.
o Inclusion of Encapsulated Postscript files (bitmap image in EPS file is
	displayed).
o Rubberbanding of ellipses/circles.
o Filled splines show areafill on screen now
        also dashed/dotted line type shows on screen
o Dot-gap and dash-length can be changed in the line-style indicator popup.

EDITING MODES
-------------

o Cut to buffer operation is now part of Copy object mode & Delete object mode.
o Update button to either update objects to current settings, or update
        indicator settings from an object.
o Rotation of certain objects by any angle (30, 45, 60, 90, 120 degrees can
	be selected using the mouse middle/right shortcut buttons).
o Alignment horizontally and/or vertically of objects to compound object edge(s)
o Objects can be scaled (not just compounds).
o Point move or object copy/move constrainable to horizontal or vertical
	movement (middle mouse button)
o Compound bounding corners shrink to fit enclosed objects and have markers
	that appear the same as other objects.
o Shift-click selection should work on all editing operations.
o Only the objects relevant to a particular editing operation will
	have their markers shown.

OVERALL OPERATION
-----------------

o Smarter redrawing (if compiled with -DFASTSERVER).
	Only the relevant objects are redrawn after an expose or after
	an edit operation (not all operations support this yet).
o Undo should work for all commands.
o Operations can now be cancelled (using the right button when appropriate).
o Point positioning to three resolutions:
	magnet (1/16inch), small grid or large grid
o TransFig 2.1 features: LaTex fonts, hidden text, scalable text, "special" text
        see TransFig man pages for description
        scalable text sizes with resizing of figure
o Attempts to save figure if signal detected (segmentation violation, etc)
o Resizing the xfig window should now be a bit smarter.
o The philosophy behind button usage has changed. This was necessary to
