OpenGL.GL.EXT.stencil_two_side

OpenGL extension EXT.stencil_two_side

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

Overview (from the spec)

This extension provides two-sided stencil testing where the stencil-related state (stencil operations, reference value, compare mask, and write mask) may be different for front- and back-facing polygons. Two-sided stencil testing may improve the performance of stenciled shadow volume and Constructive Solid Geometry (CSG) rendering algorithms.

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