I also just wrote a TGA importer and found RLE and 16-bit in
particular badly supported on Linux. E.g. eye-of-gnome
(Gnome's picture viewer) doesn't correctly restore the last
pixel's color in an RLE image and most software doesn't handle
16-bit at all. Add to that, that the specs are not very
specific as to what allowed values are and you get all
sorts of funny implementations quirks.
