'''OpenGL extension ARB.texture_border_clamp
This module customises the behaviour of the
OpenGL.raw.GL.ARB.texture_border_clamp to provide a more
Python-friendly API
Overview (from the spec)
The base OpenGL provides clamping such that the texture coordinates are
limited to exactly the range [0,1]. When a texture coordinate is clamped
using this algorithm, the texture sampling filter straddles the edge of
the texture image, taking 1/2 its sample values from within the texture
image, and the other 1/2 from the texture border. It is sometimes
desirable for a texture to be clamped to the border color, rather than to
an average of the border and edge colors.
This extension defines an additional texture clamping algorithm.
CLAMP_TO_BORDER_ARB clamps texture coordinates at all mipmap levels such
that NEAREST and LINEAR filters return only the color of the border
texels.
The official definition of this extension is available here:
