'''OpenGL extension IMG.texture_env_enhanced_fixed_function
This module customises the behaviour of the
OpenGL.raw.GLES1.IMG.texture_env_enhanced_fixed_function to provide a more
Python-friendly API
Overview (from the spec)
This extension adds new texture environment functions to allow use of
of blend modes supported in some early MBX-lite devices, including dot3 functionality.
It is superceded by OpenGL-ES 1.1 which includes tex_env_combine.
New functions may be specified by calling TexEnv with the following tokens:
MODULATE_COLOR_IMG, RECIP_ADD_SIGNED_ALPHA_IMG, TEXTURE_ALPHA_MODULATE_IMG,
FACTOR_ALPHA_MODULATE_IMG, FRAGMENT_ALPHA_MODULATE_IMG, ADD_BLEND_IMG, DOT3_RGBA.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/IMG/texture_env_enhanced_fixed_function.txt
