The intention of commit 4dc20398 was to disable unredirection while
banners are shown, but the ::done-displaying signal currently used for
re-enabling unredirection is only emitted under some circumstances, so
it's possible that unredirection is left disabled indefinitely, whoops.
Fix this by tying disabling unredirection explicitly to the lifetime
of the banner actor.

When computing the effective border color, we operate on colors with
premultiplied alpha to simplify the calculations, then unpremultiply
the result. However we miss a bounds check in the last check, so any
color component can overflow the allowed maximum of 0xff and shift the
result in unexpected ways.

If the actor is not on the stage yet (i.e. does not have a theme
node), but has a paint state cached, we currently fail to invalidate
it, which will lead to the actor painting with old contents once it
gets onto the stage.
This commit fixes the issue by changing our invalidation strategy;
previously we were looking at the widget's own theme node to determine
if it should be invalidated or not.
Now we look at the theme nodes of our cached paint states. When the
widget is mapped on stage, those are the same as the widget's own
theme node, but when the widget is not on the stage, we'll still be
able to invalidate them.
As part of this, we move the invalidation API to StThemeNodePaintState,
which is a more natural place for our use case.

The only reason for `vfunc_paint` and `vfunc_pick` existing was to
implement a culling optimization. Although that optimization actually
made performance worse than none at all because it forced the painting
and picking cycles to spend more time calling into JavaScript.
Turns out we don't have to choose between native code and culling though.
Just reimplement the culling using native ClutterActor functions and we
get the benefits of both.
Performance on an i7-7700:
Moving the cursor over the icon grid:
Before: 70% CPU, 5.5ms per frame
After : 60% CPU, 4.5ms per frame
Scrolling the icon grid:
Before: 60% CPU, 4.4ms per frame
After : 50% CPU, 3.3ms per frame

In X11, pointer emulated touch events are replicated with normal PRESS, RELEASE
pair events which are generated by the server. Thus for a single tap we get:
- TOUCH_BEGIN -> TOUCH_END, PRESS -> RELEASE
This will cause st-button to send two "clicked" signals, instead of just one,
breaking extensions (like dash-to-dock) that show buttons in the main stage
which will be checked two times or that will receive the same signal two times.
Destroy the DashItemContainer's child from the same handler as the tooltip. This
will prevent invalid reads when the item is destroyed while its quicklist is
still open.

Since commit 551e827841, we don't always pass a callback parameter.
However passing it on as undefined to ibus doesn't work, as gjs doesn't
accept that as a valid callback value and throw an error. As a result,
we can end up with no layout selected in the keyboard menu and an "empty"
indicator. Fix this by explicitly passing null if no callback has been
provided.

Back in the day, there was a proposed system of tracking apps in a
specific context.
The inspiration was that you may have used apps in multiple modes:
Firefox may have been used in both "Programmer Reference" and
"Kitten Videos" contexts. Early user response to the feedback wasn't
too positive - context switching is something that humans have trouble
doing implicitly, let alone explicitly. The old codebase still has a
few remnants of this around; let's finally put them to rest.
Note that we still write out a dummy context tag to the XML file - old
versions of the shell will flat out crash if you don't have one of those
in there, so just leave it in for compatibility sake.

The pending-charge state means AC power is on but the battery is not
being charged. This can happen because its charge is above a certain
threshold, to avoid short charging cycles and prolong the battery's
life, or because the PSU is not powerful enough to charge the batteries.
Instead of lying to the user about something being estimated, we should
simply tell the truth and set the label to "Not Charging".
Closes: #701.
When we started to only show a single caption at a time, we allowed
title captions to be wider than their corresponding window preview.
But while overlapping neighboring previews is fine, we shouldn't
allow the captions to leak outside the workspace area itself and
overlap unrelated elements like workspace switcher or dash.
This partly reverts commit b3b30f239d.

Instead of defaulting to a natural scroll behavior,
have the workspace switch action use the natural-scroll setting
in org.gnome.peripherals.touchpad to determine the correct
direction of travel when swiping. 4 finger swipes will then
match the behavior of the rest of the UI.

While this sounds counter-intuitive, the image-path hint value might also
be used with URIs or icon names.
As per freedesktop standard:
The "app_icon" parameter and "image-path" hint should be either an URI
(file:// is the only URI schema supported right now) or a name in a
freedesktop.org-compliant icon theme (not a GTK+ stock ID).
Thus the image-path hint should also be parsed as it happens for the
app_icon.
Reuse same logic, by falling back on _iconForNotificationData with the
hint value.

cogl_texture_new() is used in a few places in GNOME Shell, but
it's a deprecated Cogl function. The replacement is the less
verbose cogl_texture_2d_new_with_size(), that is very much a
straightforward replacement.
Remove the few places where this function is used, replacing
it by the CoglTexture2d counterpart.

We have a callback that will call close() when the notification is
destroyed, and a callback that will call destroy() on the notification
when the message is closed.
Currently, if the notification is destroyed we'll execute our callback
that will call again destroy() on the notification. That's bad
practice in general, and it also has the side effect of resetting the
destroy reason.
This commit avoids re-destroying the notification by dropping the
notification reference on destroy.

Differently from the fd.o notifications, Gtk notifications do not
have a mechanism to update themselves. Instead, when a new
notification is received for an ID already known to the notification
daemon, the old notification is dismissed and a replaced with a new
one.
Currently though, there is no way to distinguish a notification that
was dismissed because of an user interaction, or because it was
replaced. That is an useful piece of information, so add a new value
to the NotificationDestroyedReason enum to account for it.

StTextureCache installs file monitors that invalidate caches when
contents of the underlying file change.
At the moment, the cache uses the Gio.FileMonitorEvent.CHANGED event
type to make that determination.
However, that is suboptimal for at least two reasons:
- while a file is being written to disk, many CHANGED events will be
emitted in sequence. That will cause needless cache invalidations,
and we will risk loading the file before it's fully loaded.
- if an existing file is replaced, e.g. with g_file_replace(), we may
not get a CHANGED event but a CREATED one instead, so the cache ends
up never getting invalidated.
The good news is that in both of those cases GFileMonitor will send a
CHANGES_DONE_HINT event after changes have settled, or after the file
is replaced.
This commit fixes both cases by switching from the CHANGED event to
CHANGES_DONE_HINT to determine that a file has in fact changed.

When gnome-shell receives the signal of 'set-content-type' from ibus,
gnome-shell calls KeyboardManager.holdKeyboard() and
KeyboardManager.releaseKeyboard() and the functions change the current
input focus in GNOME Xorg and it could result in closing a popup window
which has a password entry by focusing on the entry.
The solution is to stop to call the APIs on 'set-content-type' signal.

We don't usually show notification banners while the monitor is in
fullscreen, but when we do - the notification is urgent - we should
actually show the banner, even if the top-most window is unredirected.
To achieve that, disable unredirection while the banner is showing.

If the initialization fails for some reason, for example by
running 'gnome-shell --replace', we should not crash because
of an attempt of unregistering an unregistered agent handle.
Fix that by checking if the handle is not NULL before calling
the unregistering routines.

The `reactive` property of icon actors was being restored multiple times
over the course of the pulse animation, all at slightly different times
as each icon finished animating at different times.
The problem is that toggling `reactive` on an `StWidget` incurs a style
change of the `insensitive` pseudo class, and style changes would quickly
queue relayouts incurring full stage reallocation. This occurred many times
during a pulse animation, limiting its smoothness and performance.
The solution is to not toggle the `reactive` property in the pulse
animation at all, which avoids incurring multiple full stage relayouts.
As a bonus, this means the icon under the cursor pulses with the correct
selection highlight, appearing more seamless and responsive.
