glQueryCounter causes the GL to record the current time into the query object named id. target must be GL_TIMESTAMP. The time is recorded after all previous commands on the GL client and server state and the framebuffer have been fully realized. When the time is recorded, the query result for that object is marked available. glQueryCounter timer queries can be used within a glBeginQuery() /
GL_INVALID_OPERATION is generated if id is the name of a query object that is already in use within a glBeginQuery() /
GL_INVALID_VALUE is generated if id is not the name of a query object returned from a previous call to glGenQueries().
