OpenGL.GL.EXT.histogram

OpenGL extension EXT.histogram

This module customises the behaviour of the OpenGL.raw.GL.EXT.histogram to provide a more Python-friendly API

Overview (from the spec)

This extension defines pixel operations that count occurences of specific color component values (histogram) and that track the minimum and maximum color component values (minmax). An optional mode allows pixel data to be discarded after the histogram and/or minmax operations are completed. Otherwise the pixel data continue on to the next operation unaffected.

The official definition of this extension is available here: http://www.opengl.org/registry/specs/EXT/histogram.txt
