The OpenGLContext project has a number of applicable licenses. 
The majority of the code, and all core functionality is released
under the OpenGLContext License (below).

Exceptions are as follows:

	The (unfinished) module fxcontext.py is released under the 
	LGPL, and is only required and/or loaded if you use the 
	Fox/FxPy GUI library.  This module is an extremely loose
	interpretation of the FxPy gltest.py module.  Basically only
	the approach and necessary calls were taken from that module.
	
	The dek_texturesurf demo is covered under the PyOpenGL 1.5.5
	license.  See PyOpenGL's license for details.
	
	The NeHe demos and supporting media files are (c)2000 Jeff
	Molofee, see files for details.
	
	The redbook demos are Copyright (c) 1993-1999, Silicon 
	Graphics, Inc., see files for details.
	
	The obj loading module is derived from a module which is:
		Copyright (c) 2006-2008 Alex Holkner
		All rights reserved.
	see files for details.

	The GLSL shaders from the OpenGL Shading Language (2nd Ed)
	are: 

		Copyright (C) 2002-2004  3Dlabs Inc. Ltd.

	See tests/resources/3Dlabs-License.txt

	The encoded streams and decoded values in
	tests/unit/test_gltf_meshopt.py are taken from meshoptimizer's
	test suite (demo/tests.cpp), under the MIT licence:
		Copyright (c) 2016-2026 Arseny Kapoulkine
	OpenGLContext/loaders/gltf/meshopt.py is written from the
	KHR_meshopt_compression and EXT_meshopt_compression
	specifications and copies no meshoptimizer code.

	The tone curves in OpenGLContext/shaders/_tonemap_inc.glsl and
	OpenGLContext/passes/tonemapping.py follow X_ITE 16.4.3's
	ToneMapping2.glsl, and the weighted blended transparency in
	OpenGLContext/shaders/_oit_inc.glsl and OpenGLContext/passes/oit.py
	follows its OIT2 and OITCompose2 shaders, under the MIT licence:

	OpenGLContext/scenegraph/natural.py makes rocks by the method
	that the README of gl-rock (https://github.com/Erkaman/gl-rock,
	by Erkaman) describes: a sphere scraped flat in several places,
	then roughened.  The code is written from that description and
	copies none of gl-rock's code.  gl-rock is released under the
	MIT licence, whose text is given above.
