'''OpenGL extension EXT.draw_transform_feedback
This module customises the behaviour of the
OpenGL.raw.GLES2.EXT.draw_transform_feedback to provide a more
Python-friendly API
Overview (from the spec)
This extension adds the DrawTransformFeedback commands. These
were omitted from OpenGL ES 3.0 because the number of vertices
captured by transform feedback could never be different than
the number drawn during capture. The addition of geometry shaders
in OpenGL ES 3.2 broke that assumption but, due to an oversight,
DrawTransformFeedback et al were not reinstated. The
DrawTransformFeedback commands unlock the full potential of
geometry shaders.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/EXT/draw_transform_feedback.txt
