'''OpenGL extension ARB.pipeline_statistics_query
This module customises the behaviour of the
OpenGL.raw.GL.ARB.pipeline_statistics_query to provide a more
Python-friendly API
Overview (from the spec)
This extension introduces new query types that allow applications to get
statistics information about different parts of the pipeline:
* Number of vertices and primitives issued to the GL;
* Number of times a vertex shader, tessellation evaluation shader,
geometry shader, fragment shader, and compute shader was invoked;
* Number of patches processed by the tessellation control shader stage;
* Number of primitives emitted by a geometry shader;
* Number of primitives that entered the primitive clipping stage;
* Number of primitives that are output by the primitive clipping stage;
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/ARB/pipeline_statistics_query.txt
