41 /* Caveats:
42 * ! pipe_sampler_state.normalized_coords is ignored - rectangle textures will
43 * use non-normalized coordinates, everything else won't
44 * (The relevant bit is in the TIC entry and not the TSC entry.)
45 *
46 * ! pipe_sampler_state.seamless_cube_map is ignored - seamless filtering is
47 * always activated on NVA0 +
48 * (Give me the global bit, otherwise it's not worth the CPU work.)
49 *
50 * ! pipe_sampler_state.border_color is not swizzled according to the texture
51 * swizzle in pipe_sampler_view
52 * (This will be ugly with indirect independent texture/sampler access,
53 * we'd have to emulate the logic in the shader. GL doesn't have that,
54 * D3D doesn't have swizzle, if we knew what we were implementing we'd be
55 * good.)
56 *
57 * ! pipe_rasterizer_state.line_last_pixel is ignored - it is never drawn
58 *
59 * ! pipe_rasterizer_state.flatshade_first also applies to QUADS
60 * (There's a GL query for that, forcing an exception is just ridiculous.)
61 *
62 * ! pipe_rasterizer_state.sprite_coord_enable is masked with 0xff on NVC0
63 * (The hardware only has 8 slots meant for TexCoord and we have to assign
64 * in advance to maintain elegant separate shader objects.)
