Split the wrap mode of _cogl_texture_set_wrap_mode into three
GL supports setting different wrap modes for the s, t and r coordinates so we should design the backend interface to support that also. The r coordinate is not currently used by any of the backends but we might as well have it to make life easier if we ever add support for 3D textures. http://bugzilla.openedhand.com/show_bug.cgi?id=2063
