Add a CoglFrameInfo object that tracks timing information for frames that are drawn. We track a frame counter and frame timing information for each CoglOnscreen. Internally a CoglFrameInfo is automatically created for each frame, delimited by cogl_onscreen_swap_buffers() or cogl_onscreen_swap_region() calls. CoglFrameInfos are delivered to applications via frame event callbacks that can be registered with a new cogl_onscreen_add_frame_callback() api. Two initial event types (dispatched on all platforms) have been defined; a _SYNC event used for throttling the frame rate of applications and a _COMPLETE event used so signify the end of a frame. Note: This new _add_frame_callback() api makes the cogl_onscreen_add_swap_complete_callback() api redundant and so it should be considered deprecated. Since the _add_swap_complete_callback() api is still experimental api, we will be looking to quickly migrate users to the new api so we can remove the old api. Reviewed-by: Robert Bragg <robert@linux.intel.com> (cherry picked from commit 700401667db2522045e4623d78797b17f9184501)
