The legacy tray introduced as part of the notification redesign in
3.16 was meant as a stop-gap solution to encourage applications to
move away from the concept of status icons, but it hasn't really
done anything except of getting in the way. Given that the large
majority of apps that still make use of status icons work perfectly
fine without them, we decided that it is time to drop this unloved
bit of UI altogether. Users who still want them (or use one of the
odd cases where an app really depends on the icon) can install one of
various extensions that are available, either based on the XEmbed
support that is still kept around or implementing the DBus-based
StatusNotifier spec.

Currently the chrome layer decides itself which events on the window
clone should show or hide the chrome, which makes it harder to extent.
Instead, move the decision to the window clone by letting it emit
show/hide-chrome events when appropriate.

Previews are currently limited to at most 70% of the actual window
size. This was done to indicate more clearly that the overview is
active and the window cannot be interacted with. However since then
other indications like the vignette effect have been added, so
artificially limiting the preview size doesn't look necessary anymore.

Now that only one window title is visible at any time, it no longer
matters if a title extends into other window previews, so we can
always show the full title.

While the new title position gives the previews more space, they now
overlay the content which may hide valuable information. Address this
by only revealing the title as additional information on hover, like
we do for other auxiliary elements.

With the window titles no longer being shown as part of the previews
grid, we can reduce the spacing to have more space available to the
window previews themselves.

We consider the window previews the primary way to identify a window,
so it makes sense to give them as much space as possible. So in order
to not have title captions take up too much vertical space, overlay
them on top of the preview borders.

We currently expand the workspace switcher when workspaces are being
used, that is when there are any windows on a non-active workspace.
While this helps with the switcher's discoverability, it does eat into
the space available for window previews. By now the component should
be well established, so we can afford opting for space efficiency and
only expand the switcher while the user actually interacts with it.

The overview's window picker is primarily about windows, and as the
previews that represent them are more effective the bigger they are,
it makes sense to scale down competing elements; start by reducing
the size of workspace thumbnails on the right ...

Instead of potentially loading a background mid-way when it changes, and
loading it again for every file monitor event, leverage
CHANGES_DONE_HINT events, which allow us to ignore CREATED and CHANGED
signals from the file monitor.

About every other situation can do with synchronizing keyboard visibility,
and keyboard layout changes are already handled internally in the Keyboard
object.
A downside of this approach is that once created, there will always be a
Keyboard instance and its full actor hierarchy. Seems reasonable to do that
since we can't tell it won't ever be needed.
