'''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 thespec import 
  
  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 amultisampledtexture import 
     within a shader
  
   * A program option to enable the new behavior
