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.

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

Switch from St.TextureCache.load_named_icon() to using St.Icon for named
icons. Along with the advantage of getting colorization right for symbolic
icons, this allows moving some icon sizes into the CSS.
In the CSS, the system status icon size is changed to be 1em (=16px for the
default font size), at the request of the artists. See bug 613448.

Adding a "PopupMenuRadioButtonItem" wouldn't work well, because we'll
need radio-button indicators on multiple different styles of menu
item. Also, the current design draws the indicator in the menu item's
padding, so it's sort of special anyway. So just add support at the
BaseMenuItem level.
Also, redo the menu/menuitem padding so that all the horizontal
padding is in the menu item, or else the indicator dot will show up in
the wrong spot.
https://bugzilla.gnome.org/show_bug.cgi?id=631193
When there are menu items with right-aligned items, all the
right-aligned items should appear to the right of all the left-aligned
items.
Clutter doesn't have an equivalent of GtkSizeGroup, so hack something up
using ShellGenericContainer and some javascript.
https://bugzilla.gnome.org/show_bug.cgi?id=631193
Shell implemented indicators got padding from default button style,
and also spacing from their container, so too much space was left
between them. This only became apparent when more than one was
implemented, though.
Redo the way that the summary item expand/collapse animation works so
that the items all resize in unison so that when moving from one to
another, the summary area as a whole stays a constant width rather
than wobbling slightly.
(Also rename all references to the "minimum" summary item title width,
since it's not a minimum, it's just the width.)

Introduce Cairo-drawn sliders to be used in PopupMenus (for example for
volume). They are stylable to some extent (colors, border width, slider
height) and have the standard behaviour of a slider, except they are
completely modal (once you start dragging, all events are intercepted by
the slider, which thus is kept active and highlighted at all times).
They show numeric values between 0 and 1 (scaling must be performed outside)
and emit value-changed on button release, but no activate, keeping the
menu open.

All mockups now use a representation for documents/places similar to
the one used for applications. Rename AppIcon to BaseIcon and move its
code together with WellGrid out of appDisplay to stress their general
usefulness.

Extend WellGrid with an optional rowLimit parameter and an accessor
function for the grid's items, then use it to replace the custom

The shader currently forces GLSL 1.0 to avoid being incompatible with older hardware but is still using features not available in 1.0.

This patch ensures the following notifications behavior:
- Urgent notifications that have long title or banner text are auto-expanded
correctly.
- Single-line notifications that have _expandNotification() called (e.g.
because the user mouses over to them), are treated as expanded, which means
they get fully expanded if they are updated with more content and the user
can escape them.
- The position of expanded notifications is updated when they are updated.
- Notification banner is shown again on the first line if it can fully fit
there after a notification is updated, even if it was previously hidden
because the notification was expanded and the old banner did not fully fit.
- New notifications are immediately hidden if the user mouses away from them.
- If a new notification is updated while it is shown, we extend the time it
will be shown.
- If a new notification is updated while it is hiding, we stop hiding it and
show it again.
- If a summary notification is updated while it is hiding, we let it finish
hiding and show a new notification with the updated information.
Implementation details:
- Single-line notifications now have 4px bottom padding instead of 8px, which
means that their height matches the tray height, they are fully shown in the
banner mode, and don't pop out by 4px when the notification is expanded.
- Notification keeps a flag that indicates whether it is expanded, updates
its expanded look when it is updated, and emits an 'expanded' signal
indicating that its layout has possibly changed. The message tray connects
to this 'expanded' signal when it is showing a notification in the expanded
state and updates the position of the notification accordingly when this
signal is received so that the notification is fully shown. This is better
than connecting to 'notify::height' signal on the notification bin, since
it results in fewer callbacks.

The Shell is the only user of the magnifier, so there's no
reason to keep using GConf for its settings. Since it's a
session-wide tool, use a distinct schema,
org.gnome.accessibility.magnifier, stored in
/desktop/gnome/accessibility/magnifier just like before.
Put these settings in a separate schema file for clarity.
Old enums in GConf were stored as integers, we now use the
facilities provided by GSettings to save them as strings,
and convert them to integers automatically thanks to the
mapping stored in the schemas. Remove hard-coded default values,
which we can get from the schemas.

The space between the rightmost item and the edge of the screen should

The following changes make message tray look more polished:
- all notifications are now same width (no min and max width)
- there is an equal padding all around the notification (which resulted in
the increased tray height)
- action buttons are now nicely styled
- chat text box glows when focused (nevermind the unfocused look because
we'll soon always have it focused when it is showing)
- chat text has padding on the left and rounded background
- summary source buttons no longer have a border

"text-align" allows setting the alignment of text, with respect to
other lines and allocated space, without requiring a reference to
the ClutterText (which is private for most widgets).
If not specified, all text is left-aligned.
https://bugzilla.gnome.org/show_bug.cgi?id=622447
This is part of the design update for the message tray.
Source now takes an extra argument called 'title'.
All expanded message tray items are same width, which is determined by
the width of the item with the longest title, up to MAX_SOURCE_TITLE_WIDTH.
This is done so that items don't move around too much when one is expanded
and another one is collapsed.

There is currently no way of launching the desktop-wide help other

Removing the prerequisites from the gschemas.compiled rule broke
the build, as this is what triggers the generation of the actual

Instead of just restoring the former dependencies, make sure that
the schema is validated before compilation, not after.
https://bugzilla.gnome.org/show_bug.cgi?id=622050
Use GSettings for all Shell configuration. GConf is kept to read
configuration from external programs (Metacity, Nautilus and Magnifier),
but ShellGConf is removed because it's mostly useless for the few calls
we still have. Also get rid of unused GConf code in ShellAppSystem.
A basic GConf schema is still used to override Metacity defaults and
configure Magnifier in a system-wide fashion. GConf is also used as
GSettings backend via the GSETTINGS_BACKEND environment variable.
All of this will be removed when these programs have been ported
to GSettings and able to use dconf.
GLib 2.25.9 is required. Schemas are converted to the new XML format,
and compiled at build time in data/ so that the Shell can be run from
the source tree. This also requires setting the GSETTINGS_SCHEMA_DIR
environment variable both when running installed or from source tree,
in src/gnome-shell.in and src/gnome-shell-clock-preferences.in.

The shell design says that upon launching an application,

Separate out the main app view into different sections based on the categories
in the desktop file. The configuration is done via gmenu and the desktop menu

There is no support for "submenus" - only the menus directly under

Adds the ability to create one or more zoom regions that show magnified or
enhanced views of the desktop. The magnifier provides options for:
* magnification factor,
* four mouse tracking modes common to screen magnifiers,
* positioning the magnified view in one of four screen location, or full screen,
* crosshairs to accentuate the position of the mouse,
* user preferences persistence via GConf (schemas in

* a DBus API to allow other processes to drive the magnifier as a service.
https://bugzilla.gnome.org/show_bug.cgi?id=595507
Add keys for customizing the panel clock to the gconf schema and make
the clock use them. The settings are copied from gnome-panel's clock

items matches the style for applications in a couple of aspects:
* Use a gradient on hover
* Use consistent padding and spacing
https://bugzilla.gnome.org/show_bug.cgi?id=610393
This line just looks poor - it's probably a leftover from when the
panel was a gradient. We didn't quite see it before because of
a different bug where we were over-allocating the panel to 27
pixels.
To avoid visual duplication with the application menu, eliminate
the window menu button. (The window menu can still be accessed by
right-clicking on the title bar, or Alt-right-clicking anywhere on the
window.)
This is implemented using the new Mutter facility for GConf key
redirection; we add separate key for 'button_layout' with a default
that omits the menu button.
https://bugzilla.gnome.org/show_bug.cgi?id=591390
Also reorganizes the notification layout to use an StScrollView; very
tall notifications are now scrolled instead of just taking up more and
more of the screen.

Also, remove a lot of cruft from genericDisplay.js leftover from
previous St-ifications, and remove the pre-gtk-2.16 hacks from the
status tray in panel.js (which are much less needed with the
nearly-all-black panel anyway).
https://bugzilla.gnome.org/show_bug.cgi?id=614516
The actual changes to shell-menu.[ch] are pretty minimal; most of the
changes there are just style/spacing/indentation.
Also, removed shell_menu_append_separator() since it wasn't needed;
the separators would already have been behaving as intended just
because they were non-reactive.

Moving to St.Table introduced a regression that resulted in the height
of Places section to only depend on the height of the left column.
This could result into some bookmarks not being displayed at all because
there are not enough items in the left column to allocate the needed height.
Fix this by removing the St.BoxLayout actors and add the items directly to
the table.
https://bugzilla.gnome.org/show_bug.cgi?id=614144
Add a border to items which highlights on hover, just like the style

Now that we don't use pure black for the overview background
there is less incentive to soften or differentiate the top
bar using a gradient. Without a gradient it blends better
with screen bezels and reinforces the idea of being negative space.
Instead of setting a fixed size in the CSS which only works well
with a limited range of screen resolutions, assign a relative
size in the code.
While this takes away some flexibility from theme authors, it is in
line with most elements in the overview (workspaces area, dash).
Also expose the menu panes vertical alignment, so that more-apps aligns
to the workspaces area's top and more-docs to the bottom.
https://bugzilla.gnome.org/show_bug.cgi?id=610872
Limit the AppSwitcher to the screen size by either downscaling or
scrolling.
We scale the icons down up from 96, 64, 48, 32 to 22 and start scrolling
if we still fail to fit on screen.
The thumbnail box is shifted to either left or right, when failing to
fit we scroll here to.
To prevent from being offscreen at the buttom we adjust the thumbnail
height to fit.
The old positioning logic is replaced with a ShellGenericContainer to
implement a custom allocation system.

Rename WorkspacesViewSwitch to WorkspacesControls and let it manage
all workspace controls. Do not destroy and recreate the controls bar
actor on each view change, but add it to the overview once and let it

By default buttons fade from the hover to the normal state, by animating

This bug happened because the thumbnail box was only maxed, not set to 256x256.

The high level goal is to separate the concern of searching for

ShellTheme replaces both StStyle and ccss_stylesheet_t.
The interface StStylable is replaced by usage of ShellThemeNode.
A concrete node class allows some significant optimizations of property
inheritance that would have been much more difficult to achieve with
the highly abstract pair of StStylable and ccss_node_t.
Some operations that were previously on StStylable (like the
::style-changed signal) are directly on NtkWidget.
Custom properties are no longer registered as param-specs; instead you
call directly into shell theme node to look up a length or color:
shell_theme_node_get_length (theme_node, "border-spacing", FALSE, &spacing);
The dependency on libccss is dropped, while preserving all existing
functionality and adding proper parsing and inheritance of font properties
and proper inheritance for the 'color' property.

a CSS bug where *.some-class was needed instead of .some-class are removed.

Remove the last use of passing width into Dash by having the
Pane with the previews scaling dynamically and relying on
Clutter scaling.
If we only have one workspace, don't display a selection frame

Rework Dash into a searchArea and sectionArea, which get
explicitly sized by overlay.js. We use the workspaces size

Switch dash colors/boxes etc. to ones from shell-black02.
Add a gradient to the panel.
Add a magnifier.svg for use in search.
We only want to include gnome-shell.in.in in the tarball. If we

won't be correct for the install location.
Rename DocsWidget to RecentDocsWidget (as widgets for most used docs,
docs related to the currently open documents, etc. may be added in the
future), and change the title so that it doesn't abbreviate 'Docs' (for
consistency with the overlay).
Add a GConf key for favorites, and API for retrieving them.
Also add shell_app_system_lookup_basename, which we use from
the app monitor to look up WM_CLASS ids.
