| Overview |
| |
| 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. |

| |
| Add to section 5.5: |
| |
| A call to FlushRasterSGIX |
| indicates that all commands that have previously been sent to the GL |
| that would result in rasterization will complete before rasterization |
| from following commands is started. The implementation is free to |
| determine the exact point in the OpenGL pipeline at which rasterization |
| begins. |
