'''OpenGL extension SGIX.blend_alpha_minmax
This module customises the behaviour of the
OpenGL.raw.GL.SGIX.blend_alpha_minmax to provide a more
Python-friendly API
Overview (from the spec)
Two additional blending equations are specified using the interface
defined by EXT_blend_minmax. These equations are similar to the
MIN_EXT and MAX_EXT blending equations, but the outcome for all four
color components is determined by a comparison of just the alpha
component's source and destination values. These equations are useful
in image processing and advanced shading algorithms.
The official definition of this extension is available here:
