clutter_actor_allocate_preferred_size is supposed to use the fixed
position of an actor. Unfortunately, recent refactorings made it so
that it accidentally used the current allocation. As the current
allocation may be adjusted by the actor, or have been previously
allocated in a strange spot, it may have unintended side effects. Use
the fixed positioning of the actor instead.
This fixes weird issues with margins colliding with
ClutterFixedLayout, causing strange offsets on relayout.

The documentation said that you should return TRUE to mark
that the action was handled, but the code did the reverse.
Change the documentation to reflect what all the other gestures
do.

Otherwise, we'll have incorrect scrolling when we switch hardware
devices without switching virtual devices. For example, on a ThinkPad,
scroll using the touchpad, move the eraser mouse, and then scroll again:
the deltas will be wrong. This also matches what GTK+ does.

When trying to clamp to pixel a box that is exactly in between 2
pixels, the clutter_actor_box_clamp_to_pixel() function changes the
size of the box.
Here is an example :
ClutterActorBox box = { 10.5, 10, 20.5, 20};
g_message ("%fx%f -> %fx%f", box.x1, box.y1, box.x2, box.y2);
clutter_actor_box_clamp_to_pixel (&box);
g_message ("%fx%f -> %fx%f", box.x1, box.y1, box.x2, box.y2);
Here is what you get :
** Message: 10.500000x10.000000 -> 20.500000x20.000000
** Message: 10.000000x10.000000 -> 21.000000x20.000000
That is because of the properties of the ceilf and floorf function
used to do the clamping.
For example, ceil(0.5) is 1.0, and ceil(-0.5) is 0.0.
And, floor(0.5) is 0.0, and floor(-0.5) is -1.0.
To work around that problem this patch retains the distance between x
and y coordinates and apply that difference before calling ceilf() on
x2 and y2.

Export the last event received for each touch point in its entirety,
instead of duplicating ClutterEvent accessors one at a time.
examples/pan-action.c has been updated to show the type of the event
that's causing the panning.

TapAction is a GestureAction-subclass that handles clicks and
tap gestures. It is meant to provide a replacement for ClickAction
using GestureAction:
• it handles events trasparently without capturing them, so that it
can coexists with other GestureActions;
• the ::tap signal is not emitted if the drag threshold is exceeded;
• building upon GestureAction the amount of code is greatly reduced.
TapAction provides:
• tap signal, notifying users when a tap has been performed.
The image-content example program has been updated replacing its
ClickAction usage with TapAction.

Ensure that when cancelling a gesture, either because a callback
has returned FALSE or because clutter_gesture_action_cancel() has
been called, the array tracking touch points is emptied and a whole
new set of touch points is needed before restarting the gesture.
https://bugzilla.gnome.org/show_bug.cgi?id=685221
Let gesture subclasses override how the drag threshold should
be handled:
• CLUTTER_GESTURE_TRIGGER_NONE tells GestureAction that the gesture
must begin immediately and there's no drag limit that will cause
its cancellation;
• CLUTTER_GESTURE_TRIGGER_AFTER is the default GestureAction behaviour,
where it needs to wait until the drag threshold has been exceeded
before considering the gesture valid;
• CLUTTER_GESTURE_TRIGGER_BEFORE will make GestureAction cancel
the gesture once the drag exceed the configured threshold.
For example, ZoomAction and RotateAction could set
CLUTTER_GESTURE_TRIGGER_NONE since the use of two fingers makes the
begin of the action more self-evident, while an hypothetical Tap
gesture may use CLUTTER_GESTURE_TRIGGER_BEFORE to cancel the tap if
the pointer moves too much.

The code for handling key repeats (and in particular stopping on focus loss)
assumes that the repeat key is set to XKB_KEYCODE_INVALID in the default case.
This change switches to the new mechanism for loading a cursor into a buffer.
It no longer relies on having a PNG stored in a known location and instead
loads from the Wayland cursor theme.

Add support for repeating keys to the Wayland input backend.
Unfortunately the repeat delay/interval is hardcoded into the Clutter
backend, as Wayland doesn't yet tell clients what the global values
should be.

For Wayland, this is mostly the input protocol having changed, although
there's also the SHM pool API, the cursor API, as well as fullscreen and
ping.
Also port to the new (months-old) xkbcommon API, as used by Weston 0.95.
This involves having xkbcommon manage the state for us, where
appropriate. Fans of multi-layout keyboards (or just caps lock) will no
doubt appreciate these changes.

Looks like we need to include this directly, but also need to include
cogl/cogl.h to get COGL_HAS_EGL_SUPPORT, since cogl-egl.h doesn't
include cogl-defines.h first.
