'''OpenGL extension EXT.framebuffer_blit
Overview (from the spec)
This extension modifies EXT_framebuffer_object by splitting the
framebuffer object binding point into separate DRAW and READ
bindings. This allows copying directly from one framebuffer to
another. In addition, a new high performance blit function is
added to facilitate these blits and perform some data conversion
where allowed.
The official definition of this extension is available here:
http://oss.sgi.com/projects/ogl-sample/registry/EXT/framebuffer_blit.txt
Automatically generated by the get_gl_extensions script, do not edit!
