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.

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.

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.

This patch brings 'enter-event' and 'leave-event' generation for touch
based devices. This leads to adding a new API to retrieve coordinates

ClutterTexture is full of side effects that have been picked up over the
years; they make improving ClutterTexture harder than necessary, as well
as making subclassing impossible without introducing weird behaviours in
the child classes as well.
Since Clutter 1.10 we have the ClutterImage content type, which is
side-effects free, given that it just paints texture data using the
state of the actor.
Sadly, we still have subclasses of ClutterTexture, both deprecated and
not, so we cannot deprecate ClutterTexture right out; the type and
structures will still be available, like we do for ClutterGroup, but the
whole API should be moved to the deprecated section, waiting for the
time in which we can get rid of it all.
The build should not add deprecated/ into the default INCLUDE paths, so
that deprecated headers are clearly separated; this will make it easier
to get rid of them when we branch out for 2.0.
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

-Add configuration in Clutter projects to add option to build Clutter with
the GDK3 backend in addition to the Win32 backend
-Add another preconfigured clutter-config.h.win32_GDK which contains
backend configs for both GDK3 and Win32 windowing and input.
The introspection scanner has become slightly more annoying, in the hope
that people start fixing their annotations. As it turns out, it was the
right move.
It's time. Now that we have clutter_actor_allocate() respecting the
easing state of an actor, and that the LayoutManager animation virtual
functions have been deprecated, we can put ClutterAlpha on the chopping
block, and be done with it, once and for all.
So long, ClutterAlpha; and thanks for all the fish.
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.
The ClutterCanvas content implementation should be used instead, to
avoid stringing along the ClutterTexture API and implementation.
This change requires some minor surgery, as the deprecated section
already contains an header for the previously deprecated methods; plus,
we don't want to deprecate clutter_cairo_set_source_color(). This means
creating a new header to be used for Cairo-related API.
The interface looked like a good idea around the time Clutter 0.2 was
out, but in reality we never had a proper, and supported implementation
outside of clutter-gst - thus, ClutterMedia was acting like a wrapper
around GStreamer, leading to hilarious issues of impedence mismatch
between API and all sorts of indirection issues typical of wrong
abstractions.
In theory, ClutterMedia should have been deprecated and removed before
we hit 1.0, but we kept flip-flopping on the issue.
For 2.0, it's time to take it out.
And shoot it in the face.
The disjunction operator was misspelt as -O which tests whether the
following file is owned by the calling user. This doesn't take enough
arguments so bash was showing an error and the test was always
failing. This meant that NEED_XKB_UTILS was always false which should
have broken the build but the Makefile was mistakenly including
clutter-xkb-utils.c again if SUPPORT_WAYLAND is defined.

ClutterContent is an interface for creating delegate objects that handle
what an actor is going to paint.
Since they are a newly added type, they only hook into the new PaintNode
based API.
The position and size of the content is controlled in part by the
content's own preferred size, and by the ClutterContentGravity
enumeration.
Now that we have a proper scene graph API, we should split out the
rendering part from the logical and event handling part.
ClutterPaintNode is a lightweight fundamental type that encodes only the
paint operations: pipeline state and geometry. At its most simple, is a
way to structure setting up the programmable pipeline using a
CoglPipeline, and submitting Cogl primitives. The important take away
from this API is that you are not allowed to call Cogl API like
cogl_set_source() or cogl_primitive_draw() directly.
The interesting approach to this is that, in the future, we should be
able to move to a purely retained mode: we will decide which actors need
to be painted, they will update their own branch of the render graph,
and we'll take the render graph and build all the rendering commands
from that.
For the 1.x API, we will have to maintain invariants and the existing
behaviour, but as soon as we can break API, the old paint signal will
just go away, and Actors will only be allowed to manipulate the render
tree.
Dist clutter-version.h for use under non-autotools-based build
environments (e.g. MSVC) as this header is now generic under the
systems Clutter supports
Checked with Emmanuele Bassi on IRC.
The ClutterBrightnessContrastEffect effect class allows changing the
brightness and contrast levels of an actor.

Clutter applications using evdev are typically fullscreen applications
associated with a single virtual termainal. When switching away from
the applications associated tty then Clutter should stop managing all
evdev devices and re-probe for devices when the application regains
focus by switching back to the tty. To facilitate this, this patch
adds clutter_evdev_release_devices() and clutter_evdev_reclaim_devices()
functions.

This adds a NEEDS_XKB_UTILS automake conditional that's set to true if
either the wayland backend is enabled or the evdev input backend is
enabled since they both depend on clutter-xkb-utils.c and we need
to avoid listing the file twice since that leads to duplicate symbols
and the build fails.

It should be possible to adapt the abicheck.sh script so that it

the backends that were compiled into Clutter, and avoid expected

Instead of having the easing functions be dependent of ClutterAlpha, and
static to the clutter-alpha.c source file, we should make them generic
and move them to their own internal header and source files. This will
allow to re-use them in the near future.
Since Cogl has started restricting what cogl 1.x api is exposed when
COGL_ENABLE_EXPERIMENTAL_2_0_API is defined and since we build all
Clutter internals with COGL_ENABLE_EXPERIMENTAL_2_0_API defined this
patch makes a first pass at reducing our internal use of the Cogl 1.x
api.
The most notable api that's no longer exposed to us internally is
the cogl_material_ api so this switches all Clutter internals to use the
cogl_pipeline_ api instead. This patch also makes quite a bit of
progress removing internal uses of CoglHandle although there is still
more to go.
