'''OpenGL extension NV.sample_mask_override_coverage
This module customises the behaviour of the
OpenGL.raw.GL.NV.sample_mask_override_coverage to provide a more
Python-friendly API
Overview (from the spec)
This extension allows the fragment shader to control whether the
gl_SampleMask output can enable samples that were not covered by the
original primitive, or that failed the early depth/stencil tests.
This can be enabled by redeclaring the gl_SampleMask output with the
"override_coverage" layout qualifier:
layout(override_coverage) out int gl_SampleMask[];
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/NV/sample_mask_override_coverage.txt
