The completed signal is only emitted if the timeline actually completed
but when an actor is destroyed or removed from its parent the timeline
is stopped and not completed.
The workspace switch effect removes window actors from the window group
which destroys the timeline so on_$EFFECT_effect_stopped is never
called and the pointer to the timeline is dangling.

The workspace switch animation moves the WindowActors out of the
WindowGroup so if we shut down while the animation is playing the
WindowActors will have queued a destroy but will be disposed only after
the compositor is destroyed, leaving the WindowActor with a dangling
pointer.
Fix the issue by killing the workspace switch animation on shutdown.

Since the completion callback (on_switch_workspace_effect_complete) sets
priv->tml_switch_workspace1 to NULL, the unref was trying to unref NULL,
and the reffed ClutterTimeline was not getting unreffed.
This could be triggered by rapidly switching workspaces, switching again
before the animation of the initial switch was done.
Found while working on #2038.

The order of which function argument expressions are executed is
undefined, so don't rely on this for setting the background colors, as
it results in different colors on different architectures.
For example, it has been observed that the order of execution is
reversed comparing x86_64 and aarch64, making these two architectures
having different background color.
Fix this confusion, and also reproduceability in future reference tests,
by making the order of execution predictable.

MetaBackgroundActor is still necessary for culling purposes,
but now the actual rendering of the background is delegated
to MetaBackgroundContent, as well as the sizing information.

We currently assume that the actor_animate() helper function returns
a timeline. However Clutter may skip implicit animations and simple
set properties directly, for example when the actor is hidden.
The returned timeline will be NULL in that case, and we abort when
using it as instance parameter to g_signal_connect().
Fix this by only setting up a completed handler when we are actually
animating, and complete the effect directly otherwise.

We get implicit, thus auto-removed, transitions, then manage them
manually by stopping them and emitting "completed" signals. This doesn't
work since they are removed and freed when stopped. To be able to emit
the "completed" signal, hold a reference while stopping, so that we
still can emit the signal as before.

When starting standalone mutter and running using the native backend, we
always fall back on using the us pc105 keyboard layout. This can be very
frustrating if one is used to using some other keyboard layout, such as
dvorak, causing keyboard fumbling everytime when doing something with
standalone mutter.
Avoid this involuntary fumbling by having the default plugin query
localed what layout the user has actually configured the machine to
operate using. It doesn't add any keymap selection user interface, so
it'll always use the first one it encounters.

The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
Split X11 specific parts into MetaX11Display. This also required
changing MetaScreen to stop listening to any signals by itself, but
instead relying on MetaDisplay forwarding them. This was to ensure the
ordering. MetaDisplay listens to both the internal and external
monitors-changed signal so that it can pass the external one via the
redundant MetaDisplay(prev MetaScreen)::monitors-changed.

The old requirement that multiple MetaBackgroundActor objects be
layered on top of each to produce blended backgrounds resulted in
extremely inefficient drawing since the entire framebuffer had
to be read and written multiple times.
* Replace the MetaBackground ClutterContent with a plain GObject
that serves to hold the background parameters and prerender
textures to be used to draw the background. It handles
colors, gradients, and blended images, but does not handle
vignetting
* Add vignetting to MetaBackgroundActor directly.
* Add MetaBackgroundImage and MetaBackgroundImageCache to allow
multiple MetaBackground objects to share the same images
By removing the usage of ClutterContent, the following optimizations
were easy to add:
Blending is turned off when the actor is fully opaque
Nearest-neighbour filtering is used when drawing 1:1
The GLSL vignette code is slightly improved to use a vertex shader
snippet for computing the texture coordinate => position in actor
mapping.

It doesn't work now that we set the pivot point. This breaks the
maximize effect, but it fixes the destroy effect. The maximize effect
looks bad anyway, so it's not too important to me.
Switching meta/util.h to gi18n.h was wrong, mutter is a library
and needs gi18n-lib.h, but that cannot be included from a public
header (since it depends on config.h or command line options),
so split util.h into a public and a private part.

We want to show a dialog when a display change happens from the
control center. To do so, add a new vfunc to MetaPlugin and
call it when a configuration change is requested via DBus.

Instead of a full white background, make one with a random color.
This way the different "monitors" are visible and it's easier
to debug the DBus API.

All animations use the constants directly, so this is just declaring
a bunch of local variables and then doing nothing with it.
Another clang warning.
