Normally this leak goes unnoticed because basic fundamental types
are typically used with clutter_actor_animate(), the leak shows up
if boxed or object types are passed (such as ClutterVertex in the
case I stumbled upon).
The ClutterBrightnessContrastEffect effect class allows changing the
brightness and contrast levels of an actor.

We can use the __COUNTER__ macro or, failing that, the __LINE__ macro to
ensure that we don't declare dummy variables more than once with the
same name.
The comment says that we're going to load textures in a loop until we
still have work to do, or if one iteration took more than 5
milliseconds, to avoid blowing up our frame budget, but the check is for
5 seconds, which is hardly a sensible value.
We remove 2 pixels from the height of the cursor, but we should also
remove the same amount from the position on the y axis, so that the
cursor caret appears centered in the allocated height.

ClutterScript should be able to automatically call gettext() and friends
on strings loaded from a UI definition, prior to passing the string to
the object it is constructing.
The basic implementation is trivial:
- set a translation domain on the ClutterScript instance
- mark the translatable strings inside the JSON data, like:
"property" : {
"translatable" : true,
"string" : "a translatable string"
}
The hard part is now getting the tools we use to extract the
translatable strings to understand the JSON format we use inside
ClutterScript.
Let's keep a budget of 16.6 milliseconds per frame, and reduce it by the
amount of time spent in each phase of the frame processing. If any phase
goes over the allocated budget then we use the diagnostic mode
facilities to warn the app developer.
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.
In theory, handlers connected to the ::allocation-changed signal may be
able to modify the actor's real allocation and allocation flags,
especially now that we use STATIC_SCOPE; let's avoid this, so that we
don't regret it later.
The show and hide implementation inside ClutterStage ended up being
recursive, and the hide implementation would actually show the children
of the stage unconditionally.
Whoopsie.
The ActorBox passed to the ::allocation-changed signal should be
annotated as STATIC_SCOPE, given that it's a pointer to a structure
inside ClutterActorPrivate - hence there's no risk of it actually being
freed from a signal handler. This allows the GSignal machinery to avoid
a costly copy/free for each signal emission.
If the redraw entry is not cleared, queueing a redraw from a signal
handler could reinsert the same object in the stage redraw list,
causing the segfault later (as the object is immediately freed)

This just adds some padding pointers so that we can later add more
virtual functions without breaking ABI.

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.

When using the Wayland backend this sets a constraint that the
CoglRenderer selects the Wayland EGL winsys.
When a Wayland compositor display is set it now also sets a constraint
that the render should use EGL because only EGL renderers will set up
the required wl_drm global object.
The X11 backend now sets the X11 constraint.

The core input devices when XInput doesn't work were being created as
generic ClutterInputDevices instead of ClutterInputDeviceX11s. This
meant the keycode_to_evdev virtual wouldn't work.

This adds a virtual function to ClutterInputDevice to translate a
keycode from the hardware_keycode member of ClutterKeyEvent to an
evdev keycode. The function can fail so that input backends that don't
have a sensible way to translate to evdev keycodes can return FALSE.
There are implementations for evdev, wayland and X. The X
implementation assumes that the X server is using an evdev driver in
which case the hardware keycodes are the evdev codes plus 8.

Because evdev isn't associated with the display system, it doesn't
have any easy way to associate an input device with a stage.
Previously Clutter would never set a stage for an input device and
leave it up to the application to set it. To make it easier for
applications which just have a single fullscreen stage (which is
probably the most common use case for evdev) the device manager now
associates all input devices with the first stage that is created
unless something has already set a stage.

This adds a signal that's emitted whenever a wayland surface is damaged
that allows sub-classes to override the default handler to change
how clipped redraws are queued if the sub-class doesn't simply draw
a rectangle. The signal can also be used just to track damage.

This adds a NEEDS_XKB_UTILS automake conditional that's set to true if
