  39 /* Caveats:
  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.)
  43  *
  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.)
  47  *
  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
  53  *     good.)
  54  *
  55  *  ! pipe_rasterizer_state.line_last_pixel is ignored - it is never drawn
  56  *
  57  *  ! pipe_rasterizer_state.flatshade_first also applies to QUADS
  58  *    (There's a GL query for that, forcing an exception is just ridiculous.)
  59  *
  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.)
  63  *
  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.)
