Neil Roberts 99c651d2b4 Move the add_swap_buffers_callback functions out of the winsys
Instead of having each winsys implement its own list of callbacks the
list is now just attached directly to the CoglOnscreen using code in
cogl-onscreen.c. The winsys's can invoke this list of callbacks by
calling _cogl_onscreen_notify_swap_buffers(). All of the winsys's
would probably have a very similar implementation for this anyway and
I don't think it makes much sense to try and save the cost of a list
pointer in the CoglOnscreen struct.
