Ok, on the NV10 the current code:
1) too *many* band-like textures: there should be other kinds there
   as well.
2) too many colors in the same texture, or probably too different colors.
   There should probably be a dominant color, several shades of it and
   possibly a highlight color that's very different. Now there are
   just too many colors. Jvk: apparently, here as well, saving bits
   applies.
