This causes very low performance in some situations (like multiscreen). Proper
fixes are too invasive at this point (3.8.1) so lets just remove the shadow
for now and add it back later once he have fixed it.

It turns out that we never destroyed modal dialogs when closing
them, causing them to still linger in the scene graph even when
there were no references to them in the JS. The one case where
we don't want to destroy modal dialogs after being closed is
endSessionDialog, so provide a parameter that allows classes
to override this behavior.

We chain up on _finish() to drop the grab and destroy the switcher
popup but we should activate the target window first because dropping
the grab results in the previously focused windows getting a focus in
event immediately followed by the focus out event from the target
window activation which we can easily avoid.

This ensures that when we have windows that are already visible,
like desktop icons, they don't fly across the screen from what
seems to be hyperspace to get into view.

if a slideshow file has a really large duration we'll currently
throw an exception.
This bug is aggravated by the fact that some versions of
gnome-desktop use UINT_MAX as a sentinel value to mean,
"don't ever update slide".
This commit treats durations that would overflow as infinitely
long.

If a background gets requested from the cache while it's still
being loaded from an earlier call, then there will be two concurrent
loads of the same file.
That concurrency is mitigates the effectiveness of the cache and
also causes leaks.
This commit consolidates file loads so that concurrency doesn't
happen.

Right now we only destroy the bgManager object when the
workspaceThumbnail is explicitly destroy with its destroy()
method.
This commit makes sure bgManager gets destroyed when the
workspaceThumbnail actor is destroyed without calling
destroy().

BackgroundManager connects to the changed signal in
the backgrounds it manages.
The signal ids for the changed signal connectionss are stored
as state on the background manager object.
If the background being managed changes while the manager
is still loading the old background, then the signal id
variable can get out of sync with the background object being
managed.
This commit ties the signal id to the background objects themselves,
so there is no opportunity for them to desynchronize.

Normally backgrounds get evicted from the cache when their actor is
destroyed. If the actor changes content without destroying itself,
though, we should evict the old content from the cache, too.
https://bugzilla.gnome.org/show_bug.cgi?id=696157
We currently only add the first instance of a background
to the cache. This means if the actor associated with that
background is destroyed, the content will be evicted and
it will need to get reloaded, even if it's already loaded
on another actor.
This commit ensures every content gets added to the cache.
