RE: Xpm, VC++, etc.

Yes, they do PBM internally, but it looks like they don't do PPM at all. GNU's color icons are all in XPM. (They do duplicate the icons used by tree-widget.el in PNG). I don't see that PBM is a huge win over XBM, which I assume we already do internally for Windows. I don't think there are any pixmap formats that are simple enough to do internally (except maybe Windows BMP, which I know nothing about). The problem is that there are just too many ways to tweak pixmap representations, and people want the formats they use to handle several varieties.

XPM has always been a hairy icky thang epitomizing the whole X11 swamp, but libpng, netpbm, libjpeg, and zlib are pretty bullet-proof and have been stable for years.
