'''OpenGL extension NV.texture_border_clamp
This module customises the behaviour of the
OpenGL.raw.GLES2.NV.texture_border_clamp to provide a more
Python-friendly API
Overview (from the spec)
OpenGL ES provides only a single clamping wrap mode: CLAMP_TO_EDGE.
However, the ability to clamp to a constant border color can be
useful to quickly detect texture coordinates that exceed their
expected limits or to dummy out any such accesses with transparency
or a neutral color in tiling or light maps.
This extension defines an additional texture clamping algorithm.
CLAMP_TO_BORDER_NV clamps texture coordinates at all mipmap levels
such that NEAREST and LINEAR filters of clamped coordinates return
only the constant border color. This does not add the ability for
textures to specify borders using glTexImage2D, but only to clamp
to a constant border value set using glTexParameter.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/NV/texture_border_clamp.txt
