This adds API to let you override the choice of Cogl's winsys backend. Previously it was only possible to override the winsys using the COGL_RENDERER environment variable, but it's useful for something like Clutter to be able to control the winsys via API without needing environment variable tricks. This also adds API to query back the winsys chosen by Cogl, in case you don't set an explicit override. Signed-off-by: Neil Roberts <neil@linux.intel.com>
