Due to the way add_device() invariably adds to the master/slave device
lists, while keeping ClutterInputDevices 1:1 with device IDs, it may
leave invalid pointers in the list if add_device() is called multiple
times for the same device ID. There are two situations where this may
happen:
1) If devices are disabled and later enabled: devices are added invariably
to the master/slave lists on constructed(), but then on XIDeviceEnabled
they'd get added yet again.
2) Racy cases where the ClutterDeviceManager is created around the same time
XIHierarchyEvents are sent. When getting the XIDeviceInfo on constructed(),
these devices may already appear as enabled, even though XIDeviceEnabled
is seen through XIHierarchyEvents processed in the event loop sortly after.
This last case can be seen when starting gnome-shell on a different tty,
and entering in the one it's been spawned on, clutter initialization
happens around the same time devices are added back because of the tty
switch, and multiple extra ClutterInputDevices are created.

Dispose() may be called more than once, so calling g_free directly
on the device name is unsafe. Instead, use g_clear_pointer() to
make sure we don't attempt to free the memory again.

When support for implicit animation of actor position was added,
the optimization for not queueing when allocating an actor back
to the same location was lost. This optimization is important
since when we are hierarchically allocating down from the top of
the stage we constantly reallocate the actors at the top of the
hierarchy back to the same place.
https://bugzilla.gnome.org/show_bug.cgi?id=719368
When the source actor potentially changes size, that shouldn't
necessarily result in the target actor being redrawn - it should
be like when a child of a container is reallocated due to changes
in its siblings or parent - it should redraw only to the extent
that it is moved and resized. Privately export an internal function
from clutter-actor.c to allow getting this right.

This is necessary to avoid a deadlock with the compositor. When setting
a stage size before the stage was shown this would trigger a redraw
inside clutter_stage_wayland_resize. This redraw would result
in a call into eglSwapBuffers which would attach a buffer to the surface
and commit. Unfortunately this would happen before the role for the
surface was set. This would result in the compositor not relaying to the
client that the desired frame was shown.
With this change the call to wl_shell_surface_set_toplevel is always
made before the first redraw.

We should not create a shell surface and set the role for that shell
surface if the surface was a foreign one provided through
clutter_wayland_set_wl_surface
https://bugzilla.gnome.org/show_bug.cgi?id=699578
This adds support for optionally a providing a foreign Wayland surface
to a ClutterStage before it is first show. Setting a foreign surface
prevents Cogl from allocating a surface and shell surface for the stage
automatically.
v2: add CLUTTER_AVAILABLE_IN_1_16 annotation and API reference docs
(review from Emmanuele Bassi)
v3: set a boolean to indicate that this stage is using a foreign surface

This allows the integration of Clutter with another library, like GTK+,
that is dispatching the events itself. This is implemented by calling
into the cogl_wayland_renderer_set_event_dispatch_enabled() and since
that function must be called on the newly created renderer the newly
added clutter_wayland_disable_event_retrieval must be called before
clutter_init()
https://bugzilla.gnome.org/show_bug.cgi?id=704279
The majority of Clutter input events require a time so that that the
upper levels of abstraction can identify the ordering of events and also
work out a click count.
Although some Wayland events have microsecond timestamps not all those
that Clutter expects do have. Therefore we would need to create some
fake times for those events. Instead we always calculate our own time
using the monotonic time.
https://bugzilla.gnome.org/show_bug.cgi?id=697285
Cogl (as of 0b2b46ce) now only sets the shell surface as toplevel when
the CoglOnscreen is shown.
Without calling wl_shell_surface_set_toplevel the compositor will not
know what role to give to the compositor and thus the stage will not
appear.
When we look to support multiple roles / foreign surfaces we will need
to revisit this call and ensure we only call it when we are working in
the default case.
https://bugzilla.gnome.org/show_bug.cgi?id=703188
Since Cogl also polls on this file descriptor we can get into situations
where our event source is woken up to handle events but those events
have instead been handled by Cogl resulting in the source sitting in
poll().
We can safely rely on Cogl to handle the polling on the event source and
to dispatch those events.

When the cursor visibility changes, we have to relayout the ClutterText
actor instead of just redrawing it - as the cursor changes the
PangoLayout size, a size request cycle is needed.

When setting the font using clutter_text_set_font_description(), the
font settings on a ClutterText actor can be reset when there is a dpi
changes signaled by the backend.

Initial stage of ClutterPath migration to using float.
Naive implementation of ClutterBezier, for now the points along
the curve doesn't move at a regular speed. It is required a more
precise calculation of the length of the curve for that to happen.
Anyway the old implementation worked like this.
When destroying an actor during a drag-action with a drag_handle, the
ClutterDragAction's priv->stage could be set to NULL in _set_actor().
_dispose() must not assume that priv->stage is not NULL.

We want to avoid clutter-x11.h leaking Clutter symbols (i.e. you need to
include clutter.h yourself before including clutter-x11.h), but we need
to do so conditionally, so that ancillary stuff like gtk-doc and
g-ir-scanner get the right types while building Clutter itself.
