'''OpenGL extension NV.blend_square
This module customises the behaviour of the
OpenGL.raw.GL.NV.blend_square to provide a more
Python-friendly API
Overview (from the spec)
It is useful to be able to multiply a number by itself in the blending
stages -- for example, in certain types of specular lighting effects
where a result from a dot product needs to be taken to a high power.
This extension provides four additional blending factors to permit
this and other effects: SRC_COLOR and ONE_MINUS_SRC_COLOR for source
blending factors, and DST_COLOR and ONE_MINUS_DST_COLOR for destination
blending factors.
Direct3D provides capability bits for advertising these additional
blend modes.
The official definition of this extension is available here:
