OpenGL extension SGIX.flush_raster
This module customises the behaviour of the OpenGL.raw.GL.SGIX.flush_raster to provide a more Python-friendly API
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:
