Hi, r300 doesn't support NPOT textures fully. The only thing it supports is 2D
NPOT textures without mipmapping. That's pretty limited, but it was what D3D9
originally required. In other words, the driver shouldn't report that it
supports NPOT textures, but then we would lose GL2 support, which would be a
lot bigger problem.

There is no fix other than complete software emulation, which nobody wants.
