'''OpenGL extension OES.matrix_palette

This module customises the behaviour of the 
OpenGL.raw.GLES1.OES.matrix_palette to provide a more 
Python-friendly API

Overview (from the spec)
	
	This extension adds the ability to support vertex skinning in OpenGL ES.
	A simplified version of the ARB_matrix_palette extension is used to
	define OES_matrix_palette extension.
	
	This extension allow OpenGL ES to support a palette of matrices.  The matrix
	palette defines a set of matrices that can be used to transform a vertex.
	The matrix palette is not part of the model view matrix stack and is enabled
	by setting the MATRIX_MODE to MATRIX_PALETTE_OES.
	
	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 and weights can be changed for each vertex.  
	
	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.
