'''OpenGL extension NV.shader_thread_shuffle
This module customises the behaviour of the
OpenGL.raw.GL.NV.shader_thread_shuffle to provide a more
Python-friendly API
Overview (from the spec)
Implementations of the OpenGL Shading Language may, but are not required,
to run multiple shader threads for a single stage as a SIMD thread group,
where individual execution threads are assigned to thread groups in an
undefined, implementation-dependent order. This extension provides a set
of new features to the OpenGL Shading Language to share data between
multiple threads within a thread group.
Shaders using the new functionalities provided by this extension should
enable this functionality via the construct
#extension GL_NV_shader_thread_shuffle : require (or enable)
This extension also specifies some modifications to the program assembly
language to support the thread data sharing functionalities.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/NV/shader_thread_shuffle.txt
