| '''OpenGL extension QCOM.driver_control |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GLES2.QCOM.driver_control to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension exposes special control features in a driver to a |
| developer. A use of these controls would be to override state or |
| implement special modes of operation. One common example might be an |
| IFH or infinitely fast hardware mode. In this mode none of draw |
| commands would be sent to the GPU so no image would be displayed, |
| but all the driver software overhead would still happen thus |
| enabling developers to analyze driver overhead separate from GPU |
| performance. Some uses of this extension could invalidate future |
| rendering and thus should only be used by developers for debugging |
| and performance profiling purposes. |
| |
| The extension is general enough to allow the implementation to |
| choose which controls to expose and to provide a textual description |
| of those controls to developers. |
| |
| The official definition of this extension is available here: |
