'''OpenGL extension EXT.texture_sRGB_decode
This module customises the behaviour of the
OpenGL.raw.GLES2.EXT.texture_sRGB_decode to provide a more
Python-friendly API
Overview (from the spec)
The EXT_texture_sRGB extension (promoted to core in OpenGL 2.1)
provides a texture format stored in the sRGB color space. Sampling one
of these textures will always return the color value decoded into a
linear color space. However, an application may wish to sample and
retrieve the undecoded sRGB data from the texture and manipulate
that directly.
This extension adds a Texture Parameter and Sampler Object parameter to
allow sRGB textures to be read directly, without decoding.
The new parameter, TEXTURE_SRGB_DECODE_EXT controls whether the
decoding happens at sample time. It only applies to textures with an
internal format that is sRGB and is ignored for all other textures.
This value defaults to DECODE_EXT, which indicates the texture
should be decoded to linear color space.
The official definition of this extension is available here:
