  ----- File:        xglyph.c 
  ----- Author:      Rainer Menzner (rmz@neuroinformatik.ruhr-uni-bochum.de)
  ----- Date:        1999-09-06
  ----- Description: This file is part of the t1-library. The program xglyph
                     allows viewing of character- and string-glyphs. Diverse
		     parameters may be interactively configured.

  ----- Credits:     I want to thank IBM and the X11-consortium for making
                     their rasterizer freely available.

		     independent from X11.
