/**
 * Native bindings to the QCOM_driver_control extension.
 * 
 * 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.
