/* Caveats:
* ! pipe_sampler_state.normalized_coords is ignored - rectangle textures will
* use non-normalized coordinates, everything else won't
* (The relevant bit is in the TIC entry and not the TSC entry.)
*
* ! pipe_sampler_state.seamless_cube_map is ignored - seamless filtering is
* always activated on NVA0 +
* (Give me the global bit, otherwise it's not worth the CPU work.)
*
* ! pipe_sampler_state.border_color is not swizzled according to the texture
* swizzle in pipe_sampler_view
* (This will be ugly with indirect independent texture/sampler access,
* we'd have to emulate the logic in the shader. GL doesn't have that,
* D3D doesn't have swizzle, if we knew what we were implementing we'd be
* good.)
*
* ! pipe_rasterizer_state.line_last_pixel is ignored - it is never drawn
*
* ! pipe_rasterizer_state.flatshade_first also applies to QUADS
* (There's a GL query for that, forcing an exception is just ridiculous.)
*
* ! pipe_rasterizer_state.sprite_coord_enable is masked with 0xff on NVC0
* (The hardware only has 8 slots meant for TexCoord and we have to assign
* in advance to maintain elegant separate shader objects.)
