   1 Sampler
   2 =======
   3
   4 Texture units have many options for selecting texels from loaded textures;
   5 this state controls an individual texture unit's texel-sampling settings.
   6
   7 Texture coordinates are always treated as four-dimensional, and referred to
   8 with the traditional (S, T, R, Q) notation.

  15 wrap_s
  16     How to wrap the S coordinate. One of PIPE_TEX_WRAP.
  17 wrap_t
  18     How to wrap the T coordinate. One of PIPE_TEX_WRAP.
  19 wrap_r
  20     How to wrap the R coordinate. One of PIPE_TEX_WRAP.
  21 min_img_filter
  22     The filter to use when minifying texels. One of PIPE_TEX_FILTER.
  23 min_mip_filter
  24     The filter to use when minifying mipmapped textures. One of
  25     PIPE_TEX_FILTER.
  26 mag_img_filter
  27     The filter to use when magnifying texels. One of PIPE_TEX_FILTER.
  28 normalized_coords
  29     Whether the texture coordinates are normalized. If normalized, they will
  30     always be in [0, 1]. If not, they will be in the range of each dimension
  31     of the loaded texture.
  32 prefilter
  33     XXX From the Doxy, "weird sampling state exposed by some APIs." Refine.
  34 lod_bias
  35     The bias to apply to the level of detail.
  36 min_lod
  37     Minimum level of detail, used to clamp LoD after bias.
  38 max_lod
  39     Maximum level of detail, used to clamp LoD after bias.
  40 border_color
  41     RGBA color used for out-of-bounds coordinates.
  42 max_anisotropy
  43     Maximum filtering to apply anisotropically to textures. Setting this to
  44     1.0 effectively disables anisotropic filtering.
