'''OpenGL extension MESA.sampler_objects
This module customises the behaviour of the
OpenGL.raw.GLES2.MESA.sampler_objects to provide a more
Python-friendly API
Overview (from the spec)
This extension makes the sampler object subset of OpenGL ES 3.0 available
in OpenGL ES 2.0 contexts. As the intent is to allow access to the API
without necessarily requiring additional renderer functionality, some
sampler state that would be mandatory in GLES 3 is dependent on the
presence of additional extensions. Under GLES 3.0 or above this extension's
name string may be exposed for compatibility, but it is otherwise without
effect.
Refer to the OpenGL ES 3.0 specification for API details not covered here.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/MESA/sampler_objects.txt
