37 /* Caveats:
38 * ! pipe_sampler_state.normalized_coords is ignored - rectangle textures will
39 * use non-normalized coordinates, everything else won't
40 * (The relevant bit is in the TIC entry and not the TSC entry.)
41 *
42 * ! pipe_sampler_state.seamless_cube_map is ignored - seamless filtering is
43 * always activated on NVA0 +
44 * (Give me the global bit, otherwise it's not worth the CPU work.)
45 *
46 * ! pipe_sampler_state.border_color is not swizzled according to the texture
47 * swizzle in pipe_sampler_view
48 * (This will be ugly with indirect independent texture/sampler access,
49 * we'd have to emulate the logic in the shader. GL doesn't have that,
50 * D3D doesn't have swizzle, if we knew what we were implementing we'd be
51 * good.)
52 *
53 * ! pipe_rasterizer_state.line_last_pixel is ignored - it is never drawn
54 *
55 * ! pipe_rasterizer_state.flatshade_first also applies to QUADS
56 * (There's a GL query for that, forcing an exception is just ridiculous.)
57 *
58 * ! pipe_rasterizer_state.gl_rasterization_rules is ignored - pixel centers
59 * are always at half integer coordinates and the top-left rule applies
60 * (There does not seem to be a hardware switch for this.)
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.)
