   7    MSAA
   8       Multi-Sampled Anti-Aliasing. A basic anti-aliasing technique that takes
   9       multiple samples of the depth buffer, and uses this information to
  10       smooth the edges of polygons.
  11
  12    TCL
  13       Transform, Clipping, & Lighting. The three stages of preparation in a
  14       rasterizing pipeline prior to the actual rasterization of vertices into
  15       fragments.
  16
  17    NPOT
  18       Non-power-of-two. Usually applied to textures which have at least one
  19       dimension which is not a power of two.
  20
  21    LOD
  22       Level of Detail. Also spelled "LoD." The value that determines when the
  23       switches between mipmaps occur during texture sampling.
  24
  25    layer
  26       This term is used as the name of the "3rd coordinate" of a resource.
  27       3D textures have zslices, cube maps have faces, 1D and 2D array textures
  28       have array members (other resources do not have multiple layers).
  29       Since the functions only take one parameter no matter what type of
  30       resource is used, use the term "layer" instead of a resource type
  31       specific one.
  32
  33    GLSL
  34       GL Shading Language. The official, common high-level shader language used
  35       in GL 2.0 and above.
