- '''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
-
- Automatically generated by the get_gl_extensions script, do not edit!
