'''OpenGL extension ARB.texture_rectangle
This module customises the behaviour of the
OpenGL.raw.GL.ARB.texture_rectangle to provide a more
Python-friendly API
Overview (from thespec import
OpenGL texturing is limited to images with power-of-two dimensions
and an optional 1-texel border. The ARB_texture_rectangle extension
adds a new texture target that supports 2D textures without requiring
power-of-two dimensions.
Non-power-of-two sized (NPOTS) textures are useful for storing video
images that do not have power-of-two sized (POTS). Re-sampling
artifacts are avoided and less texture memory may be required by
using non-power-of-two sized textures. Non-power-of-two sized
textures are also useful for shadow maps and window-space texturing.
However, non-power-of-two sized textures have limitations that
do not apply to power-of-two sized textures. NPOTS textures may
not use mipmap filtering; POTS textures support both mipmapped
and non-mipmapped filtering. NPOTS textures support only the
GL_CLAMP, GL_CLAMP_TO_EDGE, and GL_CLAMP_TO_BORDER wrap modes;
POTS textures support GL_CLAMP_TO_EDGE, GL_REPEAT, GL_CLAMP,
GL_MIRRORED_REPEAT, and GL_CLAMP_TO_BORDER (and GL_MIRROR_CLAMP_ATI
and GL_MIRROR_CLAMP_TO_EDGE_ATI if ATI_texture_mirror_once is
supported) . NPOTS textures do not support an optional 1-texel
border; POTS textures do support an optional 1-texel border.
NPOTS textures are accessed by dimension-dependent (aka
non-normalized) texture coordinates. So instead of thinking of
the texture image lying in a [0..1]x[0..1] range, the NPOTS 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).
