The AnimatedIcon does not have an API for controlling the animation but
relies on the :visible property changes to start and stop a timeout used
to update the frame.
This has the inconvenient of having a side effect when visible is set to
true multiple times, and is not really the API expected from such
component. Also, there is a race if it is displayed before the images
are loaded: there is no child yet and thus we get this._frame = NaN
which leads to a crash.
Switch to a play/stop API instead, and add a load event callback to the
TextureCache.load_slice_image to exactly know when we can start using
the images.

As we now allow the ctrl-alt-tab popup on the lock screen, it should
be possible to navigate back from the top bar, so add the corresponding
elements to the switcher.
https://bugzilla.gnome.org/show_bug.cgi?id=688202
The original condition the property was based on was added to make
the a11y switcher available in the login screen, though it did never
work properly - after popping up the switcher, additional tab key
presses were ignored. As we are now able to filter bindings much more
selectively, we can simplify the check and drop the sessionMode property.

With the new flexible system in place, there's no point explicitly
hardcoding some built-in keybindings; just use the generic mechanism
for everything.
https://bugzilla.gnome.org/show_bug.cgi?id=688202
Currently we hardcode the set of keybindings that are available in the
overview; add a generic mechanism to specify in which KeybindingModes
a keybinding should be available.

For now we just use it to assign an identifier to modal modes in
which we want to allow some keybindings, but we don't use it for
any actual filtering; we'll start doing this shortly.

We are currently using a hack to allow a select set of keybindings
in the overview. Implement the new MetaPlugin keybinding_filter
hook, which provides a cleaner way to achieve the same.

It appears to be somewhat common for st_widget_style_changed() to be
called when no style-relevant attributes have, in fact, changed. Now that
we cache theme nodes, we're likely to get the same theme node back from
the cache. If we do, we don't need to waste time asking whether its
geometry and painting are equal to itself: we can just note that nothing
really changed and get on with our lives.

If you copy a theme node's paint state into itself, it should be an
inexpensive no-op. What actually happened was that we destroyed the
old paint state, re-initialized to blank, then copied the blank state
back into itself. In the process, we lost (for instance) the textures
for rounded corners.
Until I introduced the texture cache, this never actually happened,
because when st_widget_recompute_style() calls st_widget_get_theme_node(),
we'd always get a fresh theme node. Now, we get a theme node T back
from the cache, notice that paint_equal(T, T) is true, short-circuit
slightly by copying its drawing state into itself, and destroy drawing
state that we still needed.
I'm going to fix this in recompute_style() too, but as a general
principle, self-assignment ought to be harmless.

Because we calculate and cache CSS properties once per StThemeNode,
and only a certain set of attributes can affect the CSS properties,
it's advantageous for as many widgets as possible to share a single
StThemeNode. Similarly, if a widget changes state and then changes back
(e.g. gaining and losing the :hover pseudo-class), it should ideally
get its original StThemeNode back again when it returns to the old
state.
Here, I'm using the StThemeContext as the location for a cache.
StThemeNodes are currently never freed: this seems OK for Shell's usage
(a finite number of IDs, classes, pseudo-classes and types).

The screen grabber was a workaround for an extremely slow path in Mesa
when reading back pixel data from the frame buffer. It was using pixel
buffer objects by directly calling into GL to hit a fast blit path in
Intel's driver. This should no longer be necessary with the latest
Mesa because the normal read pixels path now has a fast path to just
memcpy the data. Using PBOs in that case just adds an extra
indirection because the data is read into an intermediate buffer and
then copied back out again.
We want to be able to remove the dependency on linking against libGL
directly from Gnome Shell because that will not work if Cogl is
actually using GLES. Also libGL includes GLX which means gnome-shell
ends up with a hard dependency on Xlib which hinders the goal of
getting Gnome Shell to be a Wayland compositor.

When updating the dash, we already avoid all animations while the
overview is hidden. However, as we are using Main.queueDeferredWork(),
updates may be deferred up to ~20 seconds while the overview is hidden.
If the overview is entered before a queued update has taken place, it
will be run immediately on map - as the overview is visible by then,
this means animating any outstanding changes.
Work around this by skipping animations during overview transitions as
well.

If the session mode has no locking support, screenshield had code to

If I click on "Not listed?" in the login screen, I come to a username
field with two buttons: "Cancel" and "Sign In".
Clicking on "Sign In" doesn't actually sign me in though - it takes me
to the login entry. It would be better to rename "Sign In" to "Next" for
the username stage, therefore.
Gdm emit a signal to ask a question or a secret, but we can not know if
this is the last authentication question, hence we only use "Sign In"
for secret questions which improve the situation a lot.

When in the overview, if you move the mouse cursor over one of the
application launchers in the dash, all the unrelated windows are dimmed
both both in the window view and in the workspace view.
It helps to easily understand whether or not there are already opened
windows for this application, and where they are. It can also help in
differentiating the windows in the overview (sometimes the thumbnails
aren't precise enough to easily know which thumbnail belongs to which
application).
