OpenGL.GL.SUN.slice_accum

OpenGL extension SUN.slice_accum

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

Overview (from the spec)

This extension defines a new accumulation operation which enables the accumulation buffer to be used for alpha compositing. This enables higher precision alpha blending than what can be accomplished using the blend operation.

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