| /* 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.half_pixel_center is ignored - pixel centers |
| * are always at half integer coordinates and the top-left rule applies |
| * (There does not seem to be a hardware switch for this.) |
| * |
| * ! 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.) |
