'''OpenGL extension OES.matrix_get
This module customises the behaviour of the
OpenGL.raw.GLES1.OES.matrix_get to provide a more
Python-friendly API
Overview (from the spec)
Many applications require the ability to be able to read the
GL matrices. OpenGL ES 1.1 will allow an application to read
the matrices using the GetFloatv command for the common profile
and the GetFixedv command for the common-lite profile.
In cases where the common-lite implementation stores matrices
and performs matrix operations internally using floating pt
(example would be OpenGL ES implementations that support JSR184 etc.)
the GL cannot return the floating pt matrix elements since the float
data type is not supported by the common-lite profile.
Using GetFixedv to get the matrix data will result in a loss of
information.
To take care of this issue, new tokens are proposed by this
extension. These tokens will allow the GL to return a
representation of the floating pt matrix elements as as an array
of integers, according to the IEEE 754 floating pt "single format"
bit layout.
Bit 31 represents the sign of the floating pt number.
Bits 30 - 23 represent the exponent of the floating pt number.
Bits 22 - 0 represent the mantissa of the floating pt number.
The official definition of this extension is available here:
