'''OpenGL extension NV.texture_shader2
This module customises the behaviour of the
OpenGL.raw.GL.NV.texture_shader2 to provide a more
Python-friendly API
Overview (from the spec)
This extension extends the NV_texture_shader functionality to
support texture shader operations for 3D textures.
See the NV_texture_shader extension for information about the
texture shader operational model.
The two new texture shader operations are:
<conventional textures>
22. TEXTURE_3D - Accesses a 3D texture via (s/q,t/q,r/q).
<dot product textures>
23. DOT_PRODUCT_TEXTURE_3D_NV - When preceded by two DOT_PRODUCT_NV
programs in the previous two texture shader stages, computes a
third similar dot product and composes the three dot products
into (s,t,r) texture coordinate set to access a 3D non-projective
texture.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/NV/texture_shader2.txt
