'''OpenGL extension ARB.fragment_layer_viewport
This module customises the behaviour of the
OpenGL.raw.GL.ARB.fragment_layer_viewport to provide a more
Python-friendly API
Overview (from the spec)
The geometry shader has the special built-in variables gl_Layer and
gl_ViewportIndex that specify which layer and viewport primitives
are rendered to. Currently the fragment shader does not know which
layer or viewport the fragments are being written to without the
application implementing their own interface variables between
the geometry and fragment shaders.
This extension specifies that the gl_Layer and gl_ViewportIndex
built-in variables are also available to the fragment shader so the
application doesn't need to implement these manually.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/ARB/fragment_layer_viewport.txt
