onscreen: Add CoglFrameInfo and _add_frame_callback() api 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.

cogl/onscreen: Let swap buffer caller create frame info We currently have mutter set a global frame counter on the frame info in the native backend, but in order to do this from clutter, change the frame info construction from being implicitly done so when swapping buffers to having the caller create the frame info and passing that to the swap buffers call. While this commit doesn't introduce any other changes than the API, the intention is later to have the caller be able to pass it's own state (e.g. the global frame count) along with the frame info. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1285

* The presentation time measured in microseconds, is based on
cogl: Make presentation time always MONOTONIC This concerns only the cases when the presentation timestamp is received directly from the device (from KMS or from GLX). In the majority of cases this timestamp is already MONOTONIC. When it isn't, after this commit, the current value of the MONOTONIC clock is sampled instead. The alternative is to store the clock id alongside the timestamp, with possible values of MONOTONIC, REALTIME (from KMS) and GETTIMEOFDAY (from GLX; this might be the same as REALTIME, I'm not sure), and then "convert" the timestamp to MONOTONIC when needed. An example of such a conversion was done in compositor.c (removed in this commit). It would also be needed for the presentation-time Wayland protocol. However, it seems that the vast majority of up-to-date systems are using MONOTONIC anyway, making this effort not justified. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1484>

onscreen: Add CoglFrameInfo and _add_frame_callback() api 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.

cogl: Report presentation time in microseconds KMS and GLX device timestamps have microsecond precision, and whenever we sample the time ourselves it's not the real presentation time anyway, so nanosecond precision for that case is unnecessary. The presentation timestamp in ClutterFrameInfo is in microseconds, too, so this commit makes them have the same precision. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1484>
