Recreating icons on every style change -- like hover, can have
disasterous effects. Not only is the quick creation/destruction of
the actors bad, but adding/removing actors at runtime queues many
relayouts, which makes the whole system slower as a lot of unnecessary
reallocations are figured out.
While an optimization was here before, it was broken because it
broke high-contrast themes. Connect explicitly to the texture cache
to know when the icon theme has changed, instead of removing a valuable
optimization.

We explicitly include NoDisplay applications in the ShellAppSystem because
we want app tracking for them, but we explicitly filter NoDisplay applications
out when showing them to the user because we don't want to show them to the
user. We also based our "All" apps view on a flattened list of apps. While
we did check for NoDisplay on the app item itself, we didn't check against
its parents. Refactor the app display view to not use a separate flat list
of applications, but instead a concatenation of all the applications in all
the loaded categories.

clutter_actor_get_children requires making a temporary GSList from
a linked list structure, and then creating a JS Array from that GSList.
For simple cases like the number of children, use clutter_actor_get_n_children.

When displaying children, we need to make sure that we use the rowLimit
property that we pass to iconGrid, rather than assuming that it's
always MAX_SEARCH_RESULTS_ROWS in case some subclass (in an extension maybe)
wants to do something different.

Commit 26580f8f reintroduced an optimization on style changes to avoid
creating icons unconditionally. As this breaks icon theme changes (for
instance when toggling "High Contrast" in the universal access menu),
remove it again.

IconGrid items used to be square, so a single size value made
perfect sense. However, as contact search uses rectangular items,
using a single size is wrong - the allocated height ends up twice
the size of the visible height, which is particularly visible if
another provider displays results below contact results.

If both spacing and -shell-grid-item-size are 0, as they would be with nothing
setting them, we enter an infinite loop where we try to compute the layout.
Avoid the situation entirely by defaulting -shell-grid-item-size to a sane
value instead of 0.
https://bugzilla.gnome.org/show_bug.cgi?id=662747
Forcing the icon size will distort it unnecessarily, and will
in any case not work if showing an animation (which is a ClutterGroup).
Instead, set the size on the bin, and make it align its child
if needed.

The last patch in the sequence. Every place that was previously
setting prototype has been ported to Lang.Class, to make code more
concise and allow for better toString().
https://bugzilla.gnome.org/show_bug.cgi?id=664436
All classes that have at least one other derived class (and thus
benefit from the framework) have been now ported. These includes
NMDevice, SearchProvider, AltTab.SwitcherList, and some other
stuff around.

js2-mode is no longer developed and we recommend js-mode these days,
so switch the modelines to specify that, and make them consistent
across all files.

Currently the icon texture is only updated on style changes when
the icon size is set from CSS and differs from the previously used
icon size.
As the style change may have been triggered by an icon theme change,
textures that are created for themed icons should always be recreated;
given that this is the case for most uses (with the exception of
file thumbnails), recreate the icon texture unconditionally to avoid
complexity.
https://bugzilla.gnome.org/show_bug.cgi?id=643738
Mainly due to StTextureCache's way of handling fallback icons, an
implementation of BaseIcon.createIcon() may return an icon smaller
than the requested size. Given that BaseIcon is not used for isolated
elements, but rather for groups of related items (App view, Dash,
Search Results, ...), having some elements end up with the wrong
size is more annoying than having some elements end up ugly due to
scaling, so explicitly enforce the requested icon size.
https://bugzilla.gnome.org/show_bug.cgi?id=642043
- Center the icon texture in the area allocated for it, and always give
the nominal size - avoid off-by-one scaling if the parent allocated
a little less or more size than we wanted.
- Use Math.floor() when centering horizontally to avoid allocation
at a half pixel.

Currently there is a serious problem with ellipsization in various
parts of the overview. While wrapping the label or giving it more
space may be appropriate approaches for the application view, neither
works very well for the dash - possibly the best option there is to
not show the label at all.
So add a constructor parameter to BaseIcon to allow hiding the
label.
https://bugzilla.gnome.org/show_bug.cgi?id=636156
As all children were considered for the grid's layout, hidden items showed up as
empty space. Instead, exclude hidden children from the layout, so that the grid is
only made up of visible items.
https://bugzilla.gnome.org/show_bug.cgi?id=631537
Although within St itself there are situations where the semantics of
these functions (return TRUE or FALSE and return the actual value in
an out parameter) is useful, it's mostly just annoying at the
application level, where you generally know that the CSS property is
going to specified, and there is no especially sane fallback if it's
not.
So rename the current methods to lookup_color, lookup_double, and
lookup_length, and add new get_color, get_double, and get_length
methods that don't take an "inherit" parameter, and return their
values directly. (Well, except for get_color, due to the lack of (out
caller-allocates) in gjs.)
And update the code to use either the old or new methods as appropriate.

Both current design and new mockups use square icons. Currently this
is implemented by setting a fixed width and height in the CSS, which
does not work for the growing/shrinking items in the new sidebar.
By moving the assumption of square items into the code, the size will
adjust according to icon size, spacing, padding and font size if not
explicitly overwritten in the CSS.
https://bugzilla.gnome.org/show_bug.cgi?id=625887
The current design features a sidebar where the icon size shrinks
automatically to fit more items. Add a setSizeManually parameter
to BaseIcon, which disables sizes read from CSS and allows to use
BaseIcon.setIconSize() to support this.
https://bugzilla.gnome.org/show_bug.cgi?id=625887
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.
