All the cogl_rectangle* APIs normalize their input into into an array of _CoglMutiTexturedRect rectangles and pass these on to our work horse; _cogl_rectangles_with_multitexture_coords. The definition of _CoglMutiTexturedRect had 4 separate float members, x_1, y_1, x_2 and y_2 which meant for some common cases we were having to copy out from an array into these members. We are now able to simply point into the users array avoiding a copy which seems desirable when submiting lots of rectangles.
