SUMMARY
Under versions of Win32s prior to 1.25, a device-independent bitmap (DIB)
is limited to a size of 2.3 MB. This size was chosen to accomodate a bitmap
of 1024 by 768 pixels at 24 bits per pixel.
In Win32s 1.25a, this limit was increased to 1280 by 1024 pixels at 24 bits
per pixel.
This limit can cause a variety of problems to occur, such as painting
problems with SetDIBitstoDevice() if a larger bitmap is used.
