OpenGL extension EXT.blend_minmax
This module customises the behaviour of the OpenGL.raw.GL.EXT.blend_minmax to provide a more Python-friendly API
Overview (from the spec)
Blending capability is extended by respecifying the entire blend equation. While this document defines only two new equations, the BlendEquationEXT procedure that it defines will be used by subsequent extensions to define additional blending equations.
The two new equations defined by this extension produce the minimum (or maximum) color components of the source and destination colors. Taking the maximum is useful for applications such as maximum projection in medical imaging.
