OpenGL extension ARB.explicit_attrib_location
This module customises the behaviour of the OpenGL.raw.GL.ARB.explicit_attrib_location to provide a more Python-friendly API
Overview (from the spec)
This extension provides a method to pre-assign attribute locations to named vertex shader inputs and color numbers to named fragment shader outputs. This allows applications to globally assign a particular semantic meaning, such as diffuse color or vertex normal, to a particular attribute location without knowing how that attribute will be named in any particular shader.
