/**
* SECTION:cogl-texture-rectangle
* @short_description: Functions for creating and manipulating rectangle
* textures for use with non-normalized coordinates.
*
* These functions allow low-level "rectangle" textures to be allocated.
* These textures are never constrained to power-of-two sizes but they
* also don't support having a mipmap and can only be wrapped with
* %COGL_PIPELINE_WRAP_MODE_CLAMP_TO_EDGE.
*
* The most notable difference between rectangle textures and 2D
* textures is that rectangle textures are sampled using un-normalized
* texture coordinates, so instead of using coordinates (0,0) and
* (1,1) to map to the top-left and bottom right corners of the
* texture you would instead use (0,0) and (width,height).
*
* The use of non-normalized coordinates can be particularly
* convenient when writing glsl shaders that use a texture as a lookup
* table since you don't need to upload separate uniforms to map
* normalized coordinates to texels.
*
* If you want to sample from a rectangle texture from GLSL you should
* use the sampler2DRect sampler type.
*
* Applications wanting to use #CoglTextureRectangle should first check
* for the %COGL_FEATURE_ID_TEXTURE_RECTANGLE feature using
* cogl_has_feature().

* <note>Unlike for #CoglTexture2D textures, coordinates for
