'''OpenGL extension SGIX.flush_raster
Overview (from the spec)
This extensions provides a way to ensure that all raster operations
currently in the pipeline will be completed before the next
raster operation begins. We define a raster operation as an operation
that involves the rasterization stage of the OpenGL pipeline.
The implementation is free to decide what consitutes flushing the
raster subsystem.
The motivation is to allow accurate instrumentation by
including this call before stopping rasterization measurements.
There are cases where Finish() is used, but a FlushRaster()
would suffice, so this extension is deliberately kept independent
of the instruments extension.
The official definition of this extension is available here:
http://oss.sgi.com/projects/ogl-sample/registry/SGIX/flush_raster.txt
