'''OpenGL extension NV.compute_shader_derivatives
This module customises the behaviour of the
OpenGL.raw.GL.NV.compute_shader_derivatives to provide a more
Python-friendly API
Overview (from the spec)
This extension adds OpenGL and OpenGL ES API support for the OpenGL
Shading Language (GLSL) extension "NV_compute_shader_derivatives".
That extension, when enabled, allows applications to use derivatives in
compute shaders. It adds compute shader support for explicit derivative
built-in functions like dFdx(), automatic derivative computation in
texture lookup functions like texture(), use of the optional LOD bias
parameter to adjust the computed level of detail values in texture lookup
functions, and the texture level of detail query function
textureQueryLod().
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/NV/compute_shader_derivatives.txt
