Simply use St's existing key navigation system by making all the window
clones StWidgets, and making the WorkspacesView a focus group.
Since the workspace view is effectively "fake", we need to add a focus
delegator so that when key focus is assigned to the fake workspaces page,
we can keynav inside it properly.

Before, workspacesOnlyOnPrimary was implemented in quite a crazy manner:
* If workspacesOnlyOnPrimary was false, we'd create one WorkspacesView per
monitor, with the primary one being a bit special.
* If workspacesOnlyOnPrimary was true, we'd create one WorkspacesView, and
additional montiors would be handled inside that WorkspacesView as
"extra workspaces".
This caused numerous bugs as the two modes weren't consistently
implemented, and a lot of code was duplicated between all the modes.
Fix this by always creating WorkspaceViews, even if it only handles
one interface. We do this by having two different WorkspacesView-ish
classes: WorkspacesView handles the traditional combination of lots
of workspces, and a new ExtraWorkspaceView is in control of only one
workspace.
Right now, the workspace update code is complex and spread across parts:
WorkspacesView takes a set of workspaces and looks like it owns them, but
WorkspacesDisplay is actually in charge of setting them up and creating
new ones for each WorkspacesView.
Change initialization and handling to move all of the creation/destruction
responsibilities to WorkspacesView.
We pass in monitorIndex into each WorkspacesView, which is a lie in the
workspacesOnlyOnPrimary case, as the primary WorkspacesView currently has
the responsibility of handling the extra workspaces on all the other
monitors. The commit will clean this up and punt the responsibility back
to WorkspacesDisplay.
Commit 16fa186b63 attempted to fix the zoom animation problem
by throwing changes on the floor while the overview is animating. This has
the side effect that we might end up missing some positioning changes causes
windows to overlap the workspace thumbnails.
So revert those changes and fix it by simply by passing
WindowPositionFlags.ANIMATE during the overview animation.
This way the animation works as expected and we don't miss any position changes.

When the allocation of the workspacesView changes during the animation we override
the tween with one that does not animate causing the overview zoom animation
not to happen.
Fix that by ignoring the alloactionChanged notification during the overview
animation.
If we created a workspace after showing the view, we would never
set the geometry on it, which would cause an exception in the
window layout code and leave the DND state tracking in an undefined
state.

Instead of doing an entire recalculation of window positions when
sliding the thumbnails box, simply recalculate the position and scale
with basic aspect ratio math. This also ensures that windows won't
miraculously swap positions, even if we reposition windows while the
thumbnails box is expanded.
https://bugzilla.gnome.org/show_bug.cgi?id=694469
As we want to eventually track two geometries, we need to rename
our very plain "_x, _y, _width, _height". While we could just prefix
them, I think that stuffing them in an object makes more sense.
At the same time, make the variable and method name more descriptive
by adding such a prefix, as well as a bit of documentation.
https://bugzilla.gnome.org/show_bug.cgi?id=694469
To ensure that we don't recalculate window layouts when zooming
in or out, we need to always pass the full geometry. This will
break window repositioning when we zoom back in; for the purposes
of commit clarity, this breaks this feature for now. It will be
added back soon.

DND of windows has a lot of side effects, including the possibility of
current workspace disappering from under our feet. We need to account
for that when trying to activate it.

When a swipe scroll completes, we scroll the active workspace into
view. This works fine if the gesture is completed properly by
emitting 'gesture-end', but not when Clutter considers the gesture
cancelled - in that case, the view remains stuck in an intermediate
position. To fix, treat 'gesture-cancel' the same as 'gesture-end'.
https://bugzilla.gnome.org/show_bug.cgi?id=689394
Both WorkspacesDisplay and ThumbnailsBox need to know when windows have been
restacked. Instead of each tracking changes on their own or trying to call
each other, have the overview keep track and do the calculations, emitting
a signal with the result.
https://bugzilla.gnome.org/show_bug.cgi?id=690175
The thumbnail controls are not a separate actor in the overview group
yet, so we need to ensure a spacing between them and the workspaces
view.
Instead of exporting the overview spacing, just add a temporary style
class to the workspaces-view actor for it. It will be removed in the
future when we change the layout of overview elements.
https://bugzilla.gnome.org/show_bug.cgi?id=690174
On additional monitors the workspacesView takes up the entire monitor
and in some cases windows in overview can end up hard against the
edge of the monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=688133
Ouch. This went unnoticed for a long time as by default (using
dynamic workspaces) only one workspace is added at a time, which
happens to work fine.
