61f2d751d0 tap-action: Add TapAction, to handle mouse/touch tapping
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.

950e60f824 x11: Add EventSequence → touch detail accessor
The ClutterEventSequence structure is a fully opaque type; on X11, it is
just an unsigned integer that gets converted into a pointer, but in the
future it may become a fully fledged data structure.

Obviously, we cannot tell people to just dereference the pointer into an
integer in order to use it, and still retain the ability to change the
type; for this reason, we need a proper accessor function to convert the
EventSequence into a touch detail, to be used with the XInput API.

9ca06d2895 pan-action: add PanAction, to handle panning in scrollable actors
PanAction is a GestureAction-subclass that implements the panning
concept for scrollable actors, with the ability to emit interpolated
signals to emulate the kinetic inertia of the panning. PanAction provides:

• pan signal, notifying users of the panning gesture status;

• pan-stopped signal, emitted at the end of the interpolated phase
  of the panning gesture, if enabled;

• pan-axis property, to allow constraining the dragging to a specific
  axis;

• interpolated property, to enable or disable the inertial behaviour;

• deceleration property, to customize the rate at which the momentum
  of the panning will be slowed down;

• acceleration-factor property, applied to the inertial momentum when
  starting the interpolated sequence.

An interactive test is also provided.

436ebb2716 gesture-action: add _get_motion_delta()/_get_velocity()
Add some accessors to simplify common tasks for GestureAction users:

• clutter_gesture_action_get_motion_delta() to get the delta
  on the X and Y axis in stage coordinates since the last motion
  event, and the scalar distance travelled;

• clutter_gesture_action_get_velocity() to get an estimate of the
  speed of the last motion event along the X and Y axis and as a
  scalar value in pixels per millisecond.

9e02ef459e input-device: add enter/leave events generation for touch events
This patch brings 'enter-event' and 'leave-event' generation for touch
based devices. This leads to adding a new API to retrieve coordinates

0afc137918 Revert "layout-manager: Add a new animation API"
This reverts commit 7f6b17bc50.

ClutterLayoutManager implementations should just defer the easing state
set up to the child, and not try to impose a global one.

1eb869ec8f Add ClutterGridLayout
ClutterGridLayout is port of GtkGrid to a Clutter layout manager. All
the logic is taken from gtkgrid.c, so all the credits should go to
Matthias Clasen for writing this nice piece of code.

ClutterGridLayout supports adding children with it's own methods
GridLayout.attach() and GridLayout.attach_next_to() as well as
Actor.add_child() and friends. The latter adds children in a similar
fashion to ClutterBoxLayout

65c8b11604 image: Add a data setter using GBytes
The plain C bytes array, while convenient from a C perspective, is not
well handled by language bindings: the length of the array is not
specified, and it's only just implied by the image data size, rowstride,
and pixel format.

GBytes is a read-only bytes buffer that has an implicit length; we can
use it as the storage medium so that language bindings can actually
function correctly.

7f6b17bc50 layout-manager: Add a new animation API
It's similar to to the implicit animation API of ClutterActor and
compatible to deprecated API of ClutterBoxLayout and
ClutterTableLayout.

It adds :use-animations, :easing-mode, :easing-duration and
:easing-delay properties to control animations when allocation of a
child has changed. Layout manager implementers should call

use_animations = clutter_layout_manager_get_easing_state (manager,
                                                          &mode,
                                                          &duration,
                                                          &delay);

from the allocate() virtual function to access these values.

c500fc1844 Add ClutterTransitionGroup
The TransitionGroup class is a logical container for running multiple
transitions.

TransitionGroup is not a Score: it is a Transition that advances each
Transition it contains using the delta between frames, and ensures that
all transitions are in a consistent state; these transitions are not
advanced by the master clock.

1511e588df actor: Add delay to the easing state
It should be possible to set up the delay of a transition, but since
we start the Transition instance before returning control to the caller,
we cannot use clutter_actor_get_transition() to do it without something
extra-awkward, like:

  transition = clutter_actor_get_transition (actor, "width");
  clutter_timeline_stop (transition);
  clutter_timeline_set_delay (transition, 1000);
  clutter_timeline_start (transition);

for each property involved. It's much easier to add a delay to the
easing state of an actor.

229607464b Improve repaint functions
It is sometimes useful to be able to have better control on when a
repaint function is called. Currently, all repaint functions are called
prior to the stages update phase of the frame processing.

We can introduce flags to represent the point in the frame update
process in which we wish Clutter called the repaint function.

As a bonus, we can also add a flag that causes adding a repaint function
to spin the master clock.
