OpenGL.GL.NV.explicit_multisample

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
