'''OpenGL extension NV.transform_feedback2

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

Overview (from thespec import 
  
  The NV_transform_feedback and EXT_transform_feedback extensions allow
  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 encapsulating 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 DrawTransformFeedbackNV() 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.

The official definition of this extension is available here:
