If I had to guess, my guess is that it's probably applications that
either assume:
- The system visual is the same as the GdkRGB visual (this breaks
on dual 8bit/24bit systems, etc, but was a common GTK+-1.x
programming mistake.)
- The GdkRGB visual is the same as imlib's visual. (probably would
work on most "normal" systems.)
