/**
* Native bindings to the EXT_occlusion_query_boolean extension.
*
* This extension defines a mechanism whereby an application can query whether any pixels (or, more precisely, samples) are drawn by a primitive or group
* of primitives.
*
* The primary purpose of such a query (hereafter referred to as an "occlusion query") is to determine the visibility of an object. Typically, the
* application will render the major occluders in the scene, then perform an occlusion query for each detail object in the scene. On subsequent frames,
* the previous results of the occlusion queries can be used to decide whether to draw an object or not.
