| '''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: |
| http://www.opengl.org/registry/specs/SGIX/flush_raster.txt |
