'''OpenGL extension ARB.transform_feedback2

This module customises the behaviour of the 
OpenGL.raw.GL.ARB.transform_feedback2 to provide a more 
Python-friendly API

Overview (from the spec)
	
	The EXT_transform_feedback extension allows applications to capture 
	primitives to one or more buffer objects when transformed by the GL.
	This extension provides a few additional capabilities to these extensions,
	making transform feedback mode more useful.
	
	First, it provides transform feedback objects which encapsulate transform
	feedback-related state, allowing applications to replace the entire
	transform feedback configuration in a single bind call.  Second, it
	provides the ability to pause and resume transform feedback operations.
	When transform feedback is paused, applications may render without
	transform feedback or may use transform feedback with different state and
	a different transform feedback object.  When transform feedback is
	resumed, additional primitives are captured and appended to previously
	captured primitives for the object.
	
	Additionally, this extension provides the ability to draw primitives
	captured in transform feedback mode without querying the captured
	primitive count.  The command DrawTransformFeedback() is equivalent to
	glDrawArrays(<mode>, 0, <count>), where <count> is the number of vertices
	captured to buffer objects during the last transform feedback capture
	operation on the transform feedback object used.  This draw operation only
	provides a vertex count -- it does not automatically set up vertex array
	state or vertex buffer object bindings, which must be done separately by
	the application.
