With support for boolean constants in g-i, we can finally use the

7249b11899 background: Don't silently fizzle out when removing bad content from the cache
If the background is already removed, or we're trying to remove bad content,
this is probably a bug in content accounting, so let us crash so we can fix
the bugs.

586ebcd5be background: fix asynchronous management of background loading operations
This fixes a blue background being drawn when switching the monitors
configuration using hardware keys
(clone/multimonitor/external/internal).

The problem is that the shell gather all background loading requests
under the same meta_background_load_file_async call using one
GCancellable (the first one to come). So when the shell receives a
batch of 12 or so XRandr events, it creates 12 new background managers
which end up trying to load 12 times the same background picture. All
of these requests are batched into the same
meta_background_load_file_async using the first GCancellable received
on the first request. Unfortunately, when the first request is
cancelled by the following event indicating a new monitor setup, all
of the background picture requests are dropped on the floor, and
nothing gets loaded (hence the blue screen background).

1dadcee5c9 background: don't choke on huge slide show durations
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.

bed3bb45f7 background: don't load the same image more than once concurrently
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.

f920fd8b6f background: properly disconnect background signals
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.

b9da6d9ef6 background: When updating actor content, evict old content from cache

3be489c69e background: always add content to cache
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.

570fc68cb1 main: put noise texture below startup animation, not still frames
Right now we take a still frame of the desktop before showing the
start up animation.  This gives us an animation over what was
there before startup.

That's not actually desirable when restarting the shell.  We don't
want to animate over undecorated windows, we really want to animate
over the noise texture.

This commit drops the still frames in favor of the noise texture.

d5e647a191 ScreenShield: fix positioning of background with multimonitor
Previously, we would create one StBin per monitor, but each was positioned
at 0,0 and sized as the screen, so they would overlap and draw the box shadows
on top of the other backgrounds.
Instead, we need to size appropriately the bin, and then we need to position
the actual MetaBacgroundActor at 0,0, so add a flag to BackgroundManager
for this.
Also, get rid of MetaBackgroundGroup, they do nothing because the screenshield
is not a descendant of the MetaWindowGroup and because the widget in between
blocks the propagation of the visible region. At the same time, use a
widget, not a bin, because StBin requires you to set .child, not call add_child().
