Currently adding a new session mode requires patching the sources.
As defining custom modes can be desirable in some circumstances
(for instance for administrators of kiosk setups), load additional
modes from JSON files.

Now that we use the new 'switch-applications' keybinding for the
application-based alt-tab popup, we can use the 'switch-windows'
keybinding for a more traditional switcher.
Based heavily on the alternate-tab extension from Giovanni Campagna.

The Shell's alt-tab popup is application-based, so using the
'switch-windows' keybinding for it never really made sense.
Use the newly added 'switch-applications' keybinding instead.

Decorations are fairly uncommon in gnome-shell, so it's
worthwhile to avoid effort creating empty attr lists. This
can also help prevent a relayout.

Coverity rightly complained about the context < 0 comparison.
In addition, context was shadowing the parameter of the same
name, and the loops over the attributes were unnecessarily
running all the way.

If the chosen action is not open, the tray should not be closed, to
let the user further interact with it (for example to mute or remove
more sources)

This is meant to expose the global.session_mode to applications such
as the gnome-tweak-tool, which would need it to differentiate between
the vanilla GNOME Shell mode and the fallback replacement mode.

This was due to incorrect pixel clamping, which bounced the height
of the actor between values. Just remove pixel clamping, as Clutter
will correctly do it for us.

This doesn't (or shouldn't) change the visual appearance of the fade
effect, but does do all the testing math inside the shader, rather
than on the CPU. This will make fading the offset much easier in
the future.

GLSL 1.20 is a better language, and we'll rely on it in future updates.
This doesn't have any additional constraints, since GLSL 1.20 was
standardized before GLSL-supporting drivers came out.

Currently we assume that either the initial sessionMode will have
the overview or none of the pushed modes - starting without the
overview and pushing a mode that adds it fails spectacularly.
However this is exactly what we are going to do when loading external
modes asynchronously - we'll initially use the default mode while
the modes are loading, and switch to the mode passed on the command
line when finished. So make sure that the overview UI gets initialized
properly in that case.

Since commit 0c807bddaf, the run dialog no longer handles Escape
key presses itself but uses the action key mechanism of modal dialogs.
As the latter uses key-release events, our own handling of the Escape
key runs on key-press.
Fix this by bailing out early if anything has pushed a modal in addition
to the overview (like system modals, looking glass, ...).
