'''OpenGL extension OES.query_matrix
This module customises the behaviour of the
OpenGL.raw.GL.OES.query_matrix to provide a more
Python-friendly API
Overview (from the spec)
Many applications may need to query the contents and status of the
current matrix at least for debugging purposes, especially as the
implementations are allowed to implement matrix machinery either in
any (possibly proprietary) floating point format, or in a fixed point
format that has the range and accuracy of at least 16.16 (signed 16 bit
integer part, unsigned 16 bit fractional part).
This extension is intended to allow application to query the components
of the matrix and also their status, regardless whether the internal
representation is in fixed point or floating point.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/OES/query_matrix.txt
