'''OpenGL extension NV.texture_rectangle
This module customises the behaviour of the
OpenGL.raw.GL.NV.texture_rectangle to provide a more
Python-friendly API
Overview (from the spec)
OpenGL texturing is limited to images with power-of-two dimensions
and an optional 1-texel border. NV_texture_rectangle extension
adds a new texture target that supports 2D textures without requiring
power-of-two dimensions.
Non-power-of-two dimensioned textures are useful for storing
video images that do not have power-of-two dimensions. Re-sampling
artifacts are avoided and less texture memory may be required by using
non-power-of-two dimensioned textures. Non-power-of-two dimensioned
textures are also useful for shadow maps and window-space texturing.
However, non-power-of-two dimensioned (NPOTD) textures have
limitations that do not apply to power-of-two dimensioned (POT)
textures. NPOTD textures may not use mipmap filtering; POTD
textures support both mipmapped and non-mipmapped filtering.
NPOTD textures support only the GL_CLAMP, GL_CLAMP_TO_EDGE,
and GL_CLAMP_TO_BORDER_ARB wrap modes; POTD textures support
GL_CLAMP_TO_EDGE, GL_REPEAT, GL_CLAMP, GL_MIRRORED_REPEAT_IBM,
and GL_CLAMP_TO_BORDER. NPOTD textures do not support an optional
1-texel border; POTD textures do support an optional 1-texel border.
NPOTD textures are accessed by non-normalized texture coordinates.
So instead of thinking of the texture image lying in a [0..1]x[0..1]
range, the NPOTD texture image lies in a [0..w]x[0..h] range.
This extension adds a new texture target and related state (proxy,
binding, max texture size).
The official definition of this extension is available here:
