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).

798a0ca240 Background: don't require a URI scheme for picture-uri
Migration from old settings can result in a path instead of URI
there. This is technically invalid, but can easily recognize it
and avoid the crash.

e98c6ff31b background: when updating image remove old one from cache
We're removing the new content from the cache instead of the
old content.

9eae74357a background: don't leak background objects during quick changes
We currently let some backgrounds "fall through the cracks" if
a bunch of change notifications come in at once.

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
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.

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.

5fecd07045 background: Look at the duration per-step

17591117c1 background: Fix updating existing images that need loading
Due to weird and strange JS scoping semantics, if we are in a
callback, "i" won't be captured and when the callback is called,
we'll have the wrong index, causing addImage to be called instead
of updateImage.

020128b9ca background: don't use raise_top() since it's costly
We currently resync the stacking order of the two key frames
every iteration of the animation.  This is costly and unnecessary.

This commit ensures they're stacked properly up front and doesn't
touch them after that.

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().

b1a6940188 background: add slide show support
gnome-desktop's background drawing code supports an
XML format for presenting backgrounds based on time of day,
monitor geometry, etc. Now that we don't use gnome-desktop for drawing the
background, we need to implement that support ourselves to maintain
feature parity.

This commit implements that.

This commit updates the code to use mutter's new background
api, and changes the shell's startup animation to be closer
to the mockups.
