In keyboard/mouse wireless combos, it is rather common for the mouse to
claim it contains the multimedia keys, this makes libinput enable both
the pointer and keyboard capabilities on this device, and Clutter thus
to create a keyboard ClutterInputDevice for it.
Ideally clutter devices should be able to reflect their full capabilities,
or maybe account for the fact that certain events can be sent from
seemingly unexpected device types. But this will bring a somewhat better
behavior on such devices.

Atlasing is fine for smaller textures, but once they get too large its
downsides outweight the benefits. At worst, the larger texture will end
up inside its own atlas, but at worst it will require copying and/or
resizing of an existing atlas.
The cut-off at 512x512 pixels is a bit arbitrary, and we can change it
at any point; it would be nice if we could get the texture limit from
Cogl, and then use a fraction of that size as the cut-off limit. Sadly,
that's not portable, and it's not guaranteed to work either.
For a variety of complicated reasons, ClutterText currently sets fields
on the PangoContext when creating a layout. This causes ClutterText to
behave somewhat erratically in certain cases, since the PangoContext is
currently shared between all actors.
GTK+ creates a PangoContext for every single GtkWidget, so it seems like
we should do the same here.
Move the private code that was previously in clutter-main.c into
clutter-actor.c and clean it up a bit. This gives every actor its own
PangoContext it can mutilate whenever it wants, at its heart's content.
https://bugzilla.gnome.org/show_bug.cgi?id=739050
clutter_set_font_flags already calls clutter_backend_set_font_options,
which emits a signal which our PangoContext listens to, so this is just
duplicate and unneeded code.

libinput_suspend() will trigger the removal of input devices, but also
the emission of button/key releases pairing everything that is pressed
at that moment. These events are queued, but the ClutterInputDevice
pointers in these will point to invalid memory at the time these are
processed.
Fix this by flushing the event queue, in order to ensure there are no
unprocessed input events after libinput_suspend().

Just like unmapped children.
Apparently, layers above Clutter allow mapped children without an
allocation, instead of unmapping them. This means we need to ignore
them when computing the paint volume.

To support sub-pixel motion events coming from relative events, the
fraction part needs to be stored in the input device state as well. To
do this, simply change the current type from gint to gfloat.

If gtk_init is called after clutter_init, it can override clutter
AtkUtil implementation. In that situation, we can't say that
the accessibility is enabled, as the root object would be wrong.
In order to provide a way to prevent this:
* clutter_get_accessibility_enabled returns true of false
depending on the current AtkUtil implemented
* cally_accessibility_init always override AtkUtil implementation.
The get_threshold_tigger_egde() method was renamed to fix the typo, but
it obviously broke the ABI. To be fair, nobody in the whole of Debian
was using the symbol, apparently, so it's not like we broke existing
code. Still, it's not nice to break ABI without bumping soname, so let's
put the old symbol back in — obviously, deprecated — as a wrapper to the
newly added one.
If the device manager is created and queried for the client pointer at
a very early stage in application lifetime, the device_id returned would
be 0 as the server hasn't apparently decided yet about the client pointer.
For these situations, doing XSync prior to fetching the client pointer
gets the server to device about the client pointer before we query it.

When an application sets the scaling factor manually we should mark it as fixed
and not override it when the xsettings change. This matches GDKs behaviour.
In order for this to work we cannot use the same path when setting the value
internally so introduce a _clutter_settings_set_property_internal and use it
for that.

We need to release the temporary reference we acquired in order for the

This reverts commit 398a7ac713.
We cannot really use the GDK backend without massive regressions inside
the input layer, like touch events and gestures. The GDK backend is not
entirely up to scratch, and it's late in the cycle.
Let's land this early in 3.15, and get it up to par with X11.
Quite a few people at Guadec complained of pinpoint being broken in
speaker+fullscreen mode, with slides being half displayed. It turns
out that the X11 backend of clutter was being used and this backend
assumes the size of the current monitor is the size of the X screen
(that's not the case with multiple monitors).
To work around the shortcomings of the X11 backend we should probably
position the GDK one before. GDK implements most of the logic the
ClutterStage needs and is probably more tested.

To get correct premultiplied opacity on a canvas content, white needs
to be assigned to the color that is passed to the texture node. The
content will be very dark for lower opacity values otherwise.

xkb_state creation has been refactored out of clutter_evdev_set_keyboard_map(),
and used too in clutter_evdev_reclaim_devices(), so the xkb_state is fresh
clean after input is paused/resumed (and keyboard state possibly changed in
between)

There may be odd situations where full gesture cancellation may be wanted at once
when the first touch is lifted and ::gesture-end is emitted on a gesture action.
Although calling clutter_gesture_action_cancel() within the ::gesture-end handler
causes 2 critical warnings that are otherwise harmless.

clutter_stage_set_paint_callback() has the disadvantage that it only
works for a single caller, and subsequent callers will overwrite and
break previous callers. Replace it with an ::after-paint signal that is
emitted at the same point - after all painting for the stage is
completed but before the drawing is presented to the screen.
https://bugzilla.gnome.org/show_bug.cgi?id=732342
CLUTTER_ENTER/LEAVE might be processed too, leading to accounting of the
NULL sequence (ie. pointer) in the gesture, and fooling the gesture with
a static extra point that wouldn't go away.

Until now, touch events sort of rely on XI_Enter/XI_Leave events accompanying
the pointer emulating touch in order to have a stage set on the device, These
events won't happen though if it's not a pointer emulating touch which happens
on the stage, causing touch events to be ignored.
Fix this by ensuring that the input device has a stage on XI_TouchBegin itself,
but only if it's not already set, so we don't possibly steal touch events to
an already interacting stage.
https://bugzilla.gnome.org/show_bug.cgi?id=732234
On X11 the pointer will follow a "pointer emulating" touch sequence, so the
pointer will be effectively left inside the stage after that touch is lifted,
even though the master device stage is unset. This makes pointer events get
ignored until the pointer leaves and enters again the stage.
https://bugzilla.gnome.org/show_bug.cgi?id=732234
The 'state' field should be used for pointer events without button
information. Pointer events that have button information should use
the 'button' field.

The coordinates translated by the XI2 device manager were being clamped using
the X window size kept by StageX11. However, when the stage is fullscreen,
that size is not updated to the screen size, but kept the same in order to
allow going back to it when the stage goes out of fullscreen.

The vector of libinput and Wayland pointer axis events are in pointer
motion coordinate space. To convert to clutter's internal representation
the vectors need to be scaled to Xi2 scroll steps.
