- * @format: format of the foreign texture.
- *
- * Creates a #CoglTexture based on an existing OpenGL texture; the
- * width, height and format are passed along since it is not always
- * possible to query these from OpenGL.
- *
- * The waste arguments allow you to create a Cogl texture that maps to
- * a region smaller than the real OpenGL texture. For instance if your
- * hardware only supports power-of-two textures you may load a
- * non-power-of-two image into a larger power-of-two texture and use
