'''OpenGL extension SGIX.async_histogram
Overview (from the spec)
This extension introduces a new asynchronous mode for histogram
and minmax readbacks. It allows programs to get the contents of a
histogram or minmax table without blocking and to continue issuing
graphics commands during the readback.
The official definition of this extension is available here:
http://oss.sgi.com/projects/ogl-sample/registry/SGIX/async_histogram.txt
