'''OpenGL extension NV.explicit_multisample
This module customises the behaviour of the
OpenGL.raw.GL.NV.explicit_multisample to provide a more
Python-friendly API
Overview (from the spec)
In traditional multisample specs, the API only allows access to the samples
indirectly through methods such as coverage values and downsampled
readbacks. NV_explicit_multisample adds a set of new capabilities to allow
more precise control over the use of multisamples. Specifically, it adds:
* A query in the API to query the location of samples within the pixel
* An explicit control for the multisample sample mask to augment the
control provided by SampleCoverage
* A new texture target to wrap a renderbuffer and allow a restricted class
of accesses to the samples
* The ability to fetch a specific sample from a multisampled texture from
within a shader
* A program option to enable the new behavior
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/NV/explicit_multisample.txt
