'''OpenGL extension NV.read_depth_stencil
This module customises the behaviour of the
OpenGL.raw.GLES2.NV.read_depth_stencil to provide a more
Python-friendly API
Overview (from the spec)
Unextended OpenGL-ES 2.0 only supports using ReadPixels to read from the
default color buffer of the currently-bound framebuffer. However, it is
useful for debugging to be able to read from depth and stencil buffers.
This extension re-introduces these features into OpenGL-ES 2.0.
This document describes several extensions in order to allow an
implementation to support a subset of the total functionality.
The NV_read_depth extension allows reading from the depth buffer using
ReadPixels.
The NV_read_stencil extension allows reading from the stencil buffer using
ReadPixels.
The NV_read_depth_stencil extension allows reading from packed
depth-stencil buffers using ReadPixels.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/NV/read_depth_stencil.txt
