This dramatically thins down and sanitizes the application code.
The ShellAppSystem changes in a number of ways:
* Preferences are special cased more explicitly; they aren't apps,
they're shortcuts for an app), and we don't have many of them, so
don't need e.g. the optimizations in ShellAppSystem for searching.
* get_app() changes to lookup_app() and returns null if an app isn't
found. The semantics where it tried to find the .desktop file
if we didn't know about it were just broken; I am pretty sure no
caller needs this, and if they do we'll fix them.
* ShellAppSystem maintains two indexes on apps (by desktop file id
and by GMenuTreeEntry), but is no longer in the business of
dealing with GMenuTree as far as hierarchy and categories go. That
is moved up into js/ui/appDisplay.js. Actually, it flattens both
apps and settings.
Also, ShellWindowTracker is now the sole reference-owner for
window-backed apps. We still do the weird "window:0x1234beef" id
for these apps, but a reference is not stored in ShellAppSystem.
The js/ui/appDisplay.js code is rewritten, and sucks a lot less.
Variable names are clearer:
_apps -> _appIcons
_filterApp -> _visibleApps
_filters -> _categoryBox
Similarly for function names. We no longer call (for every app) a
recursive lookup in GMenuTree to see if it's in a particular section
on every category switch; it's all cached.
NOTE - this intentionally reverts the incremental loading code from
commit 7813c5b93f. It's fast enough
here without that.

Remove ShellGlobal's monitor-related methods, and have
Main.layoutManager provide that information instead. Move
Main._relayout() to LayoutManager, and have other objects connect to
the layout manager's 'monitors-changed' signal to know when the screen
geometry has changed.

Currently activating a window on a different workspace requires very
long drag distances, which is very inconvenient to use.
Fix that by allowing switching workspaces using the thumbnails which is
consistent with window and launcher dnd and much easier to use.

Don't do an individual hover fixup for every window overlay, instead

WorkspacesDisplay removes its dragMonitor in _dragEnd, but
this was never called in when a xdnd drag ended causing
dragMonitors to stack up and handling events multiple times.
Fix that by making sure that _dragEnd is called when xdnd ends.

We currently show the workspace in the overview in a rectangle
with the same aspect ratio as the screen. Originally this was
probably done since it showed the desktop, but we don't do this
anymore, and the positioning of the windows in the overview is
strictly a grid, so its not in any way related to monitor geometry.
Additionally, in the multihead case the screen aspect ratio is
very different from the overview monitor geometry, so a lot of
space is lost.
So, instead we just fill the entire inner rectangle of the overview
with the workspace. However, the way the zoom into and out of the
workspace right now is by scaling the workspace so that it covers
the entire monitor. This cannot really work anymore when the workspace
is a different aspect ratio. Furthermore the coordinates of the
window clone actors are of two very different types in the "original
window" case and the "window in a slot case". One is screen relative,
the other is workspace relative. This makes it very hard to compute
the cost of window motion distance in computeWindowMotion.
In order to handle this we change the way workspace actor positioning
and scaling work. All workspace window clone actors are stored in
true screen coordingates, both the original window positions and the
in-a-slot ones. Global scaling of the workspace is never done, we
just reposition everything in both the initial zoom and when the
controls appear from the side.
There is one issue in the initial and final animations, which is that
the clip region we normally have for the workspacesView will limit the
animation of the clones to/from the original positions, so we disable
the clip region during these animations.

Rather than connecting to stage::capture-event and then trying to
guess whether or not a given key-press should be handled by us or not,
handle the end-search-on-Escape case from entry::key-press-event
(since it only makes sense when the entry is focused anyway) and the
start-search-on-printable-key case from stage::key-press-event (which
will only get the events that no other actor wanted for itself).
Similarly, do exit-overview-on-Escape and switch-panes cases from
stage::key-press-event, rather than
viewSelector.actor::key-press-event, so that they will work correctly
even if the keyboard focus is somewhere else. (Also fix a longstanding
bug in the pane-switching code, which was supposed to be disabled when
a search was active, but was checking a non-existent variable.)

When the user cancels the drag while hovering over a window the timeout
handler will throw an exception because the drag actor will be destroyed
at this point.
Fix that by removing the timeout in _onDragEnd.
The xdnd timestamp gets updated on every xdnd-position event,
so while waiting for the window timeout to fire we need to make sure we
update the timestamp when getting on motion to activate the window
with the correct timestamp.
We need the view selector to extend all the way to the right edge of the
monitor, so size and position the view selector in a way that the sum of
its X position and its width add up to the primary monitor width.

As Main.overview is now usable from the view selector's constructor,

The Overview does not only hold the different elements visible in
the overview, but is also a central point to manage drag signals.
As objects which are constructed in the overview constructor cannot
access Main.overview (as its constructor has not finished yet), we
use misnamed show/hide methods to work around this limitation, which
are called when entering/leaving the overview.
A better way to handle this problem is to remove the limitation
altogether by splitting the overview constructor between internals,
which remain in the constructor, and more complex objects which
need to access Main.overview, and whose initialization is moved
to a public init() function which is called by main.js after the
overview has been constructed.

On button-release, a threshold is used to determine if the gesture
should be considered a click and thus ignored. While the drag is
active though, the controlled actor is dragged immediately. As a
result, dragging by a tiny amount does not trigger a snap back when
the action is interpreted as a click. As a fix, do not update the
dragged actor's position until the same threshold is passed.
https://bugzilla.gnome.org/show_bug.cgi?id=640494
The main overview group starts capturing events on button-press
events to implement swipe-scrolling. While reactive children of
the group which handle both button-press and button-release events
don't trigger swipe-scrolling, children that only rely on
button-release have stopped working - at least the primary/secondary
icons of the search entry are affected. While the capture handler
already checks the pointer movement between press and release to
determine whether the action should be considered a click rather
than a drag, it still blocks the release event from propagating.
Instead, only block release events for drag actions, but not for
clicks.
https://bugzilla.gnome.org/show_bug.cgi?id=640493
The workspaces view allows to drag the active workspace to swipe-scroll
to the next or previous workspace. While this behavior can come in handy
in general, there are good reasons to move the functionality to the
overview:
- Finding a spot on a workspace to start a drag can be hard,
especially when the workspace contains a single window
- With the new layout, workspaces have no visible border, making
it hard to predict where a drag can be initiated
- The same behavior is equally useful for other elements
So add setScrollAdjustment() to the overview, which allows setting
an adjustment controlled with swipe-scrolling (either horizontally
or vertically); only a single adjustment can be controlled at a
time. A swipe-scroll can be initiated on any part of the background that
is not occupied by a reactive actor. For cases where further control
is needed, 'swipe-scroll-start' and 'swipe-scroll-end' signals are
emitted.

Drag monitor functions are supposed to return a value, but
_onDragMotion() does not always do so. Add the missing return
value and remove unnecessary else.
Currently we reset the timeout on every mouse movement which means
the user has to keep the mouse at the exact same position for 1.25
seconds.
Be more tolerant and allow the user to move the mouse over the
window without reseting the timeout, which should make activating
windows easier.

GenericDisplay used to provide a common base class for places and
recent items, none of which exists anymore. As of current mockups,
display items in "Finding and Reminding" should be based on
BaseIcon / IconGrid instead.
The gnome-panel allows the user to hover over a tasklist entry
while draging to activate a minimized or obscured window and drop onto it.
Implement a similar behaviour by allowing draging to the activities button or
the hotcorner (and thus opening the overview), which allows the user to
activate any window (even on different workspaces) as a drop target.

When the user is doing a drag-and-drop, we want to temporarily show the
stage to allow them to drag to a different window. But we're not "really"
in the overview, and getting a grab would conflict with the X client doing
the drag and drop.
So add a showTemporarily()/hideTemporarily() pair of methods that show
the overview without grabbing.
This adds a lot more possibilities for asynchronous race conditions, so
rework the code to be more robust against multiple calls to show*()
and hide*(). The interpretation is now that all calls to show*() and
hide*() affect the state, but if we have conflicting calls to show and
hide we wait until the current animation is finished before correcting
to the right visual state.

According to the designers, system notifications should be transient;
so now that transient notifications are supported properly, make use
of it instead of using a timeout to remove the associated source.

As workspaces will appear as a particular view in the view selector,

The new dash implementation is a single-column vertical sidebar,
whose items are scaled dynamically to fit the available height.
If the height is still exceeded after scaling down to a minimum
item size, excess items are cut off.
The now unused old dash implementation is renamed to OldDash, as
its code will be used as a base for the new view selector element.

While scaling the desktop background with the window previews represents
workspaces quite intuitively, the approach is not without problems.
As window previews in the overview behave quite differently to "real"
windows, the representation of workspaces as miniature versions of
"real" workspaces is flawed. The scaling also makes the transitions
to and from the overview much more visually expensive, without adding
much benefit.
Leaving the background in place provides more visual stability to the
transitions and emphasizes the distinctive behavior of elements in the
overview.

The layout of recent mockups occupies the space previously reserved
