The main monitor of a window is maintained as 'window->monitor' and is
updated when the window is resized or moved. Lets avoid calculating it
every time it`s needed.
https://bugzilla.gnome.org/show_bug.cgi?id=744934
Tracking back from the monitor to the output every time we need to
figure out the scale of a window on a monitor is inconvenient, so
propagate the scale from the output to the monitor it is associated
with.

A MetaWaylandSurface was casted into a ClutterActor, but it should have
been the MetaSurfaceActor.
Move out parent_actor and surface_actor out of the loop while at it
since they won't change when iterating.
https://bugzilla.gnome.org/show_bug.cgi?id=745655
Keep the active position state in its original coordinate space, and
synchronize the surface actor with it when it changes and when
synchronizing the rest of the surface state, in case the surface scale
had changed.

We can get this operation in some cases, for example when
we're trying to resize window that cannot be resized.
This can occur with maximized windows that have a border
(without border we couldn't resize them by mouse in maximized state).
In this case we reached abort() beacuse we did not handle this op.

Previously a MetaWaylandOutput could be removed from the current outputs
table (by being unplugged for example). This would result in the global
object being removed and the MetaWaylandOutput instance freed, but the
wl_resource destructor would still try to remove itself from the list of
resources. Trying to do this, it'd try to access its user data pointer
which would point to the freed MetaWaylandOutput instance, and as a
result crash when trying to manipulate the freed data.

Whenever a MetaSurfaceActor is painted, update the list of what outputs
the surface is being drawed upon. Since we do this on paint, we
effectively avoids this whenever the surface is not drawn, for example
being minimized, on a non-active workspace, or simply outside of the
damage region of a frame.
DND icons and cursors are not affected by this patch, since they are not
drawn as MetaSurfaceActors. If a MetaSurfaceActor or a parent is cloned,
then we'll check the position of the original actor again when the clone is
drawn, which is slightly expensive, but harmless. If the MetaShapedTexture
instead is cloned, as GNOME Shell does in many cases, then these clones
will not cause duplicate position checks.
https://bugzilla.gnome.org/show_bug.cgi?id=744453
We may access it during painting even if it has been freed. For now,
manually unset it during the MetaWaylandSurface cleanup; in the future
make MetaWaylandSurface a GObject and make the surface pointer a weak
reference.

Lets use the role when doing role specific commit actions. The
conditions effectively do that anyway, and this way we will get a
compiler warning here whenever we add a new role, as well as we avoid
having different variants of role-determination checks in different
places.

Enable a user to test and debug multi output configurations on Wayland
without having the available hardware by enabling some basic
configuration of the dummy monitor manager.
Currently available configuration options are:
MUTTER_DEBUG_NUM_DUMMY_MONITORS - to set the number of monitors
MUTTER_DEBUG_DUMMY_MONITOR_SCALES - to configure the monitor scales
See src/backends/meta-monitor-manager-dummy.c for detailed description
of the available configuration parameters.

Before submitting a new scroll mode, click method or sendevents mode check if
the value is supported by the device. This avoids BadValue errors when setting
two-finger scrolling on single-finger touchpad devices since we can't easily
handle BadValue (see 9747277b)

We want to be able to deprecate macros, but right now the best we can do
is to wrap them with things like:
#ifndef CLUTTER_DISABLE_DEPRECATED
# define A_MACRO_I_WANT_TO_DEPRECATE ...
#endif
Which requires adding a new symbol to the build, and will cause a build
error instead of a compiler/pre-processor warning.
Fortunately, we can use the _Pragma() keyword introduced by C99 and
supported by GCC to add a warning to the output, while leaving the macro
itself intact.
GCC does not have a "deprecated" pragma, so we have to use a generic
warning; this also means we cannot do nifty things like concatenating
strings and the like, as we do for the "deprecated" attribute.
The macro deprecation symbol should have the same affordances as the
function deprecation one, and evaluate to nothing if the required
version is lower than the current version; or if the global toggle for
deprecation warnings is in effect.
We now have ClutterTouchpadPinchEvent and ClutterTouchpadSwipeEvent,
each bringing the necessary info for the specific gesture. Each
of these events is defined by begin/update/end/cancel phases.
These events have been also made to propagate down/up the pointer
position, just like scroll and button events do.
When binding models to actors to map items to children we don't often
need the full control of a function; in many cases we just need to
specify the type of the child we want to construct and the properties
on both the item and the child that we want to bind.
We should provide a simple convenience function that does all this for
us.
The whole of ClutterBackend is a final/protected type, so having a bunch
of instance fields and an instance private data structure is redundant
at best, and less efficient at worst.
GCC has some optimization for the inclusion guard, but they only work if
the check is the outermost one.
We're fairly inconsistent because of historical reasons, so we should
ensure that we follow the same pattern in every public header.
Use double precision floats for the intermediate computations, to avoid
loss of precision, and don't convert too integer when unnecessary, to
avoid rounding errors.
It can be useful to bind the children list to set of objects inside a
GListModel implementation; the GListModel stores the objects, and every
time the model changes, a function is called that maps each object in
the model to a newly created ClutterActor, which is then added as a
child. This API, along with the property binding one inside GObject,
allows automatic creation of views based on object models that update
themselves without manual intervention.
The model API was an ad hoc addition to Clutter, back in the 0.6 days,
that was needed because GLib did not offer anything of sort, and the
only model-like storage was inside GTK+. The API design was heavily
based on GtkTreeModel and friends, with column-based collections of
generic data.
Since then, the model API inside Clutter has not really been integrated
in the core API; on the other hand, GIO has grown a model API, and it's
seeing more use in the platform.
This means that the ClutterModel API should finally be deprecated, and
we should move code to the GListModel API inside GIO.
