'''OpenGL extension ATI.texture_float
Overview (from the spec)
This extension adds texture internal formats with 32 and 16 bit
floating-point components. The 32 bit floating-point components
are in the standard IEEE float format. The 16 bit floating-point
components have 1 sign bit, 5 exponent bits, and 10 mantissa bits.
Floating-point components are clamped to the limits of the range
representable by their format.
The official definition of this extension is available here:
http://oss.sgi.com/projects/ogl-sample/registry/ATI/texture_float.txt
