'''OpenGL extension SGIX.video_source
This module customises the behaviour of the
OpenGL.raw.GLX.SGIX.video_source to provide a more
Python-friendly API
Overview (from the spec)
This extension provides the capability to source pixel data from a
video stream. A new type of GLXDrawable (GLXVideoSourceSGIX) is
introduced which represents the drain node of a Video Library (VL)
path. A GLXVideoSourceSGIX may be specified as the <read> parameter
to glXMakeCurrentReadSGI to indicate that pixel data should be read
from the specified video source instead of from the framebuffer. A
GLXVideoSourceSGIX may only be specified as a <read> drawable.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/SGIX/video_source.txt
