* @short_description: Interface for low-level textures like
* #CoglTexture2D and #CoglTexture3D.
*
* A #CoglPrimitiveTexture is a texture that is directly represented
* by a single texture on the GPU. For example these could be a
* #CoglTexture2D, #CoglTexture3D or #CoglTextureRectangle. This is
* opposed to high level meta textures which may be composed of
* multiple primitive textures or a sub-region of another texture such
* as #CoglAtlasTexture and #CoglTexture2DSliced.
*
* A texture that implements this interface can be directly used with
* the low level cogl_primitive_draw() API. Other types of textures
* need to be first resolved to primitive textures using the
* #CoglMetaTexture interface.
*
* <note>Most developers won't need to use this interface directly but
* still it is worth understanding the distinction between high-level
* and primitive textures because you may find other references in the
* documentation that detail limitations of using
* primitive textures.</note>
