This is the bulk of the clutter-1.22 → master merge.
The clutter-1.22 branch is where the current development of Clutter
happens, and contains all the history of the project after the API
bump branch point.
Revert all the work that happened on the master branch.
Sadly, this is the only way to merge the current development branch back
into master.
It is now abundantly clear that I merged the 1.99 branch far too soon,
and that Clutter 2.0 won't happen any time soon, if at all.
Since having the development happen on a separate branch throws a lot of
people into confusion, let's undo the clutter-1.99 → master merge, and
move back the development of Clutter to the master branch.
In order to do so, we need to do some surgery to the Git repository.
First, we do a massive revert in a single commit of all that happened
since the switch to 1.99 and the API version bump done with the
89a2862b05 commit. The history is too long
to be reverted commit by commit without being extremely messy.
We rely on having the DISPLAY environment variable set, otherwise we
default to skipping all tests automatically. The TestEnvironment key
inside the installed test launcher keyfile replaces the whole
environment, instead of just adding to it like the TESTS_ENVIRONMENT
automake variable.
The easing state is part of the AnimationInfo structure, which is stored
inside the GObject's datalist. Each instance frees the data stored there
during finalization, so there is no point for us to restore an easing
state (which may or may not be the last one) just to have everything
cleared out once we chain up to GObject's own finalize() implementation.
Bind the preferred size of an actor using a BindConstraint to the
preferred size of the source of the constraint, depending on the
coordinate of the constraint.
Constraints can only update an existing allocation, which means they
live only halfway through the layout management system used by Clutter;
this limitation makes it impossible, for instance, to query the
preferred size of an actor, if the actor is only using constraints to
manage its own size.
And move the only private ClutterConstraint method to it.
This commit also sneaks in a change that makes sense for the debugging
of the update_allocation() method, which checks if the allocation was
effectively changed.
The syntax for some introspection annotations has changed between 1.38
and 1.39, so we need to bump up the dependency in order to get the new
scanner. Introspection should be updated in lock-step with GLib, so we
should also bump up the required GLib version.
The core pointer concept doesn't really exist anymore in an XI2 world,
so the clutter API is a bit of a mismatch with what X provides. Using
XIGetClientPointer doesn't really help, as far as i can tell the
semantics of XIGetClientPointer are essentially: Whatever the X server
picked when it had to reply with device-dependant data to a query
without a device specifier. Not very useful...
To make matters worse, whether XIGetClientPointer returns a valid
pointer depends on whether there has been a query that forced it to pick
one in the first place, making the whole thing pretty non-deterministic.
This patch changes things around such that instead of using
XIGetClientPointer to determine the core pointer, we simply pick the
first master pointer device. In practise this will essentially always
be the X virtual core pointer.

XIGetClientPointer() may return the device id '0' when called early.
This patch makes pointer cursors work in nested mutter Wayland
sessions again.

The installed header should not have private API declarations and
macros. Let's move those into the uninstalled clutter-backend-osx.h
header file instead.
When merging multiple definitions it's possible that the ObjectInfo
fields may get overwritten. Instead of trampling over the fields, we
should reset them only when they actually change — especially the
"is_actor" one, which controls the destruction of the objects when
unmerging happens.

We want to recompute the content box when changing the content instance,
in case the preferred size is different and the content gravity uses the
preferred size; the change of content with different preferred size and
same gravity should also trigger an implicit transition.
https://bugzilla.gnome.org/show_bug.cgi?id=711182
Some actors want to have a preferred size driven by their content, not
by their children or by their fixed size.
In order to achieve that, we can extend the ClutterRequestMode
enumeration so that clutter_actor_get_preferred_size() defers to the
ClutterContent's own preferred size.

An easing mode can be set on a frame of a KeyframeTransition.
However, the progress value of the current frame is computed using using
a linear function.
This patch adds a call to clutter_easing_for_mode() to compute
the actual progress value.
Note that parametrized easing modes (bezier and 'step') are not taken
into account.
