Scale up indicators on hover to hint at their clickability.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

Update the animation on entering/leaving the overview to only zoom
the window previews and fade other elements.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

Show a positional indicator where a new favorite will be added and
make the favorites re-orderable. Also allow the removal of favorites
using drag-and-drop according to the mockups.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

Delegate the emission of the window-drag-begin/window-drag-end
signals to overview functions, as done already for other items.
This will enable objects to react to those signals without having
access to the workspace objects / the workspaces view.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

Current mockups display all search results as icons as used by
application results, so change the default result display to use
iconGrid/BaseIcon. Remove the custom application results display,
as it is no longer needed.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

Add the view selector and adjust the positioning of elements in the
overview. Unlike the old dash, the view selector is made public to
indicate that extensions may add additional views or search providers.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

As workspaces will appear as a particular view in the view selector,
merge WorkspacesControls and WorkspacesManager to control workspaces
and related controls, so that a single actor can be added to the
selector instead of positioning the elements from the overview.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

Make the first workspace the right-most one in RTL locales, as one
would expect. Update all dragging/scrolling functions to behave
correctly.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

The new layout does no longer support view switching, so merge
GenericWorkspacesView and SingleView, and remove MosaicView.
Also rename or remove workspace properties and functions which
are now unused.
The grid will have a comeback with the new DND behavior.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

Being no longer an independent menu pane, both the toggle() and
close() functions are no longer needed, and the view's structure
can be simplified a bit.

Also update the style to fit into the view selector.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

https://bugzilla.gnome.org/show_bug.cgi?id=634948

As the view selector is a tabbed interface, use the default keyboard
shortcut of Ctrl-PageUp/PageDown of GtkNotebook for switching between
views.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

The view selector should only deal with view switching, so move the
logic to deal with search (find-as-you-type, cancelling a search,
navigating/activating results) into the SearchTab.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

The view selector is a tabbed interface with a search entry. Starting
a search switches focus to the results' tab, ending a search moves the
focus back to the previously selected tab. Activating a normal tab
while a search is active cancels the search.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

With the new layout, search results will be displayed in an independent
view like window previews, applications and possible future additions;
it does not make much sense keeping it with the switching logic, so move
the code to its own file.

Also remove the dash-prefix from the relevant style classes.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

With this change, the icons' reactive area extends to the screen
edge, making them good targets according to Fitts' law.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

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.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

As the button to add workspaces will move to the same position as
the new workspace drop area in drag mode, the latter is redundant
and can be removed.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

Overlaying inactive workspaces with a gradient to fade out the actors
does no longer work when re-using the normal desktop background. If
we keep the current DND behavior, we probably want to implement a real
fade effect - for now, just remove the visually disruptive shadows.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

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.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

The layout of recent mockups occupies the space previously reserved
for the info bar with the view selector. As the bar's purpose is
mainly to provide the user with feedback, it makes sense to use the
existing message tray facility instead of moving the bar elsewhere.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

The scrollbar is the main culprit for cluttered controls in the
linear view - all its functionality is already provided by the
workspace indicators, so it is save to remove the scrollbar in
order to clean up the interface.

https://bugzilla.gnome.org/show_bug.cgi?id=634948

Instead of hiding the drag actor temporarily to determine the actor
beneath it, make it invisible to picks while dragging using the new
shell_util_set_hidden_from_pick().

https://bugzilla.gnome.org/show_bug.cgi?id=634560

At times it is desireable to hide actors from being picked even
with a mode of CLUTTER_PICK_ALL.

Currently we use a pattern of
    clutter_actor_hide();
    clutter_stage_get_actor_at_pos();
    clutter_actor_show();
in these cases, which gets hideous if the actor we want to exclude
from the pick is located in another module.

A more elegant solution is to connect a handler to the ::pick signal,
which stops further emission.

Credit for the idea goes to Owen Taylor.

The code to draw the root background has now been moved into Mutter,
with added smarts to not draw obscured portions. Remove the old
version of the code and clone the Mutter background actor to draw
the background in the overview.

https://bugzilla.gnome.org/show_bug.cgi?id=634836

Since we always cover the stage, we don't need to clear it to a
constant color before painting the scene.

https://bugzilla.gnome.org/show_bug.cgi?id=634769

We weren't actually referencing the ShellTrayIcon actors at all
on creation, but would unreference them when they were removed,
causing crashes.

When we reference the actors, use g_object_ref_sink() so that
memory management is consistent whether or not the actors are
subsequently added to a parent actor.

Thanks for Jon McCann for help in tracking this down.

Status icons should not have tooltips according to the design.

Add an indicator for battery charge and power indication in the
system status area, using the newly exported DBus API from
gnome-power-manager.

https://bugzilla.gnome.org/show_bug.cgi?id=622451

Add a "gicon" property so that a GIcon can be used instead of an
icon name, while still getting icon recoloring from the theme.
Also include a compatibility wrapper in libshell until GJS has
support for interface static methods.

https://bugzilla.gnome.org/show_bug.cgi?id=622451

Add a "position" argument to addMenuItem, and pass it to the
underlying box layout. If undefined or null, it adds at the end.

Replaces the internal ClutterText with StLabel, so full CSS
styling is supported.

https://bugzilla.gnome.org/show_bug.cgi?id=622450

libnotify is required by gnome-settings-daemon.

gnome-volume-control-applet was renamed to gnome-sound-applet when
moved to the control-center module, so we need to check for both names
when identifying the legacy status icon.

Connect to the "changed" signal on the default icon theme, and
when it triggers:

 - Evict all cached looked up icons from the StTextureCache
 - Fake a style change on all StThemeContext; this will result
   in StIcon looking up icons again.
