40 * ! pipe_sampler_state.normalized_coords is ignored - rectangle textures will
41 * use non-normalized coordinates, everything else won't
42 * (The relevant bit is in the TIC entry and not the TSC entry.)
44 * ! pipe_sampler_state.seamless_cube_map is ignored - seamless filtering is
45 * always activated on NVA0 +
46 * (Give me the global bit, otherwise it's not worth the CPU work.)
48 * ! pipe_sampler_state.border_color is not swizzled according to the texture
49 * swizzle in pipe_sampler_view
50 * (This will be ugly with indirect independent texture/sampler access,
51 * we'd have to emulate the logic in the shader. GL doesn't have that,
52 * D3D doesn't have swizzle, if we knew what we were implementing we'd be
55 * ! pipe_rasterizer_state.line_last_pixel is ignored - it is never drawn
57 * ! pipe_rasterizer_state.flatshade_first also applies to QUADS
58 * (There's a GL query for that, forcing an exception is just ridiculous.)
60 * ! pipe_rasterizer_state.half_pixel_center is ignored - pixel centers
61 * are always at half integer coordinates and the top-left rule applies
62 * (There does not seem to be a hardware switch for this.)
64 * ! pipe_rasterizer_state.sprite_coord_enable is masked with 0xff on NVC0
65 * (The hardware only has 8 slots meant for TexCoord and we have to assign
66 * in advance to maintain elegant separate shader objects.)
