- '''OpenGL extension ARB.matrix_palette
-
- Overview (from the spec)
-
- This extension extends the abilities of ARB_vertex_blend to include
- a palette of modelview matrices. The n vertex units use a palette
- of m modelview matrices. (Where n and m are constrained to
- implementation defined maxima.) Each vertex has a set of n
- indices into the palette, and a corresponding set of n weights.
- Matrix indices can be changed for each vertex (between Begin and
- End).
-
- When this extension is utilized, the enabled units transform each
- vertex by the modelview matrices specified by the vertices'
- respective indices. These results are subsequently scaled by the
- weights of the respective units and then summed to create the
- eyespace vertex.
-
- A similar procedure is followed for normals. Normals, however,
- are transformed by the inverse transpose of the modelview matrix.
-
- The official definition of this extension is available here:
- http://oss.sgi.com/projects/ogl-sample/registry/ARB/matrix_palette.txt
