cogl provides an interface to pass along damage with the swap buffers
request. This is useful for the display servers and hardware to minimise
the work done in updating the screen and also reducing the work done by
external listeners (such as vnc, drm/udl and PRIME).

If the rectangle is allocate a size smaller than the border, drawing the
border will end up with negative coordinates, and will mess up the whole
thing. Since rectangles don't have a minimum preferred size, we cannot
rely on the allocation being big enough to contain the border and the
background color.
If the rectangle is smaller than the border width value, we just paint
the border color as well.
Point to ClutterImage, ClutterContent, and ClutterActor where needed, so
that developers trying to port their code will have a chance at figuring
out how.
Nobody has been compiling Clutter with profiling enabled in a long time.
UProf itself hasn't been updated in 5 years, and it still depends on
deprecated components like dbus-glib, with no port to GDBus in sight.
The profiling code was moderately useful in the past, but these days
it's probably better to profile Cogl than Clutter itself; timing
information can be extracted by the timestamp on each diagnostic message
that is now available by default in the CLUTTER_NOTE macro, and we can
add ad hoc counters where needed.
Add clutter_x11_set_use_stereo_stage() that can be called
before clutter_init() so that the CoglDisplay we create and all
stages created from that CoglDisplay will be created with a
stereo fbconfig.
This is done in clutter-x11 because of the similarity to the
existing clutter_x11_set_use_argb_visual(), and because it's
not clear without other examples whether the need to have
stereo enabled from before clutter_init() is universal or
somethign specific to GLX.
Cogl required version is increased to 1.20, which has the
required API.

Added support for Mir, now clutter can natively draw on MirSurfaces.
This depends on latest cogl git.
Run your clutter apps using CLUTTER_BACKEND=mir

Toolkits may need to paint actors internally outside the normal tree
(for example to create a shadow shape), in which case they need to
control the opacity directly.

The _clutter_stage_update_state() function is currently putting events
into the Clutter event queue. This leads to problems in the gdk
backend because there are assumptions upon the numbers of queued
events, and how many of them should be moved from the main event queue
to the ClutterStages' event queues.
This change triggers the processing of the state update events on the
stage directly, so the main event queue retains the expected number of
events.

If gdk event retrieval has been disabled and gdk's backend is wayland
we must also disable cogl's wayland event dispatching otherwise cogl
will try to dispatch wayland events itself which blocks the main
loop.

Pointer button events will be received from a device where a button has
been pressed, even though an equivalent button has been pressed (same
button code) on a device connected to the same seat. notify_button()
expects to only be called as if there was only one pointer device
associated with the given seat, so to achieve this, ignore every event
where forwarding it would result in multiple 'pressed' or 'released'
notifications.

Keyboard key events will be received from a device where a key has
been pressed, even though an equivalent key has been pressed (same

We are checking for Cairo ≥ 1.12 and then do an additional check for the
existence of the cairo_surface_set_device_scale() function because there
were no stable releases of Cairo with it. Now that Cairo 1.14 is out, we
can simply bump up the dependency.
libinput's API changed from separate scroll events for vert/horiz scrolling to
a single event that contains both axes if they changed.
Updated by Armin K. to use the discrete axis value for wheel events as done
in Weston.

We tried once with commit 398a7ac7 and ended up reverting because of
regressions in the input layer and on Wayland.
We should try again, now that those regressions have been fixed.

The easing state is part of the AnimationInfo structure, which is stored
inside the GObject's datalist. Each instance frees the data stored there
during finalization, so there is no point for us to restore an easing
state (which may or may not be the last one) just to have everything
cleared out once we chain up to GObject's own finalize() implementation.
