Returns the number of fragments (pixels) of the specified geometry that passed the depth test.
If is_answer_ready() did not return true, this function may block before it returns.
It is only valid to call this from the draw thread.
Implements OcclusionQueryContext.

Returns true if the query's answer is ready, false otherwise.
If this returns false, the application must continue to poll until it returns true.
It is only valid to call this from the draw thread.
Implements QueryContext.
