/**
* Native bindings to the EXT_disjoint_timer_query extension.
*
* Applications can benefit from accurate timing information in a number of different ways. During application development, timing information can help
* identify application or driver bottlenecks. At run time, applications can use timing information to dynamically adjust the amount of detail in a scene
* to achieve constant frame rates. OpenGL implementations have historically provided little to no useful timing information. Applications can get some
* idea of timing by reading timers on the CPU, but these timers are not synchronized with the graphics rendering pipeline. Reading a CPU timer does not
* guarantee the completion of a potentially large amount of graphics work accumulated before the timer is read, and will thus produce wildly inaccurate
* results. glFinish() can be used to determine when previous rendering commands have been completed, but will idle the graphics pipeline and adversely
* affect application performance.
*
* This extension provides a query mechanism that can be used to determine the amount of time it takes to fully complete a set of GL commands, and without
* stalling the rendering pipeline. It uses the query object mechanisms first introduced in the occlusion query extension, which allow time intervals to
* be polled asynchronously by the application.
*
* Requires {@link GLES20 GLES 2.0}.
