This renames the two internal functions _cogl_get_draw/read_buffer as cogl_get_draw_framebuffer and _cogl_get_read_framebuffer. The former is now also exposed as experimental API.
The current clip state implementation couldn't be used in conjunction with the CoglPath experimental API. http://bugzilla.clutter-project.org/show_bug.cgi?id=2594 Signed-off-by: Neil Roberts <neil@linux.intel.com>
