FWIW, FOX also supports the BMP and XPM image file formats.

Jeroen (FOX's author) designed FOX from the outset with portability in mind.
Because we didn't provide Mac support for our software at CFD Research
Corporation there was not a big internal push for the Mac port (plus we had
our hands full with the X and Windows versions!) IANAMP (I am not a
Macintosh programmer) but I believe a Mac port should be doable and it would
be appreciated by all.
