'''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 the spec)
	
	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).
