- Automatic texture filtering should be ok now, occasionally point filtering was used. Tested it on the ps2 and figured with no mip levels LoD and minification settings are just ignored altogether.
- Also run a few tests on the gather instruction with the reference rasterizer and found a fatal flaw with it. It returns the four samples for bilinear sampling (in a funny order, which isn't documented of course, x = bl, y = br, z = tr, w = tl), but there is no way to guess which four were selected exactly. Due to some hidden rounding error it might grab different texels than I would when calculating the position of the upper-left texel, of which the fractional part is be used for the interpolation. When the texel positions do not match it leaves annoying discontinuity errors. Oh well...

- trying the dx10.1-only "gather" shader instruction for palletized lookups ("8-bit texture" mode), saves 4 instructions which isn't much but still... (not tested, don't have ati)
- may fix the intel gma "no output" bug (don't have gma either :P)
- and the usual small code optimizations
