/**
 * Native bindings to the ARB_texture_rectangle extension.
 * 
 * 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 {@link GL11#GL_CLAMP CLAMP}, {@link GL12#GL_CLAMP_TO_EDGE CLAMP_TO_EDGE}, and
 * {@link GL13#GL_CLAMP_TO_BORDER CLAMP_TO_BORDER} wrap modes; POTS textures support {@link GL12#GL_CLAMP_TO_EDGE CLAMP_TO_EDGE}, {@link GL11#GL_REPEAT REPEAT}, {@link GL11#GL_CLAMP CLAMP}, {@link GL14#GL_MIRRORED_REPEAT MIRRORED_REPEAT}, and {@link GL13#GL_CLAMP_TO_BORDER 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).
