'''OpenGL extension SGIX.texture_scale_bias
This module customises the behaviour of the
OpenGL.raw.GL.SGIX.texture_scale_bias to provide a more
Python-friendly API
Overview (from the spec)
This extension adds scale, bias, and clamp to [0, 1] operations to the
texture pipeline.
These operations are applied to the filtered result of a texture lookup,
before that result is used in the texture environment equations and
before the texture color lookup table of SGI_texture_color_table,
if that extension exists.
These operations are distinct from the scale, bias, and clamp operations
that appear in the SGI_color_table extension, which are used to
define a color lookup table.
Scale and bias operations on texels can be used to better utilize the
color resolution of a particular texture internal format (see EXT_texture).
The official definition of this extension is available here:
