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 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.

The picked target actor may be destroyed (e.g. hover style change
resulting in the ClutterTexture to be destroyed). If we don't handle
this, GJS will abort when it sees the exception caused by Javascript
code trying to access the destroyed target actor.
To handle it, listen on the 'destroy' signal on the target actor, and
repick, so a valid actor is passed to the next motion callback.

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.

The `reactive` property of icon actors was being restored 24 times over
the course of the spring 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 spring animation hogging the CPU and limiting the frame rate.
The solution is defer and batch the cleanup for all icons until after the
last icon has finished animating. This way the CPU impact of the style
change and stage relayout isn't felt during the animation so the frame
rate remains higher and smoother. The overall CPU usage of the animation
is also reduced as the remaining relayouts are much more likely to be
grouped into a single frame.
Icon spring animation performance on an i7-7700:
Before: 83% CPU and 47 FPS
After : 78% CPU and 54 FPS
which is about a 22% increase in performance per clock (FPS/CPU).

Since we started to show OSD windows on all monitors, OSD windows are
destroyed when the corresponding monitor is disconnected. We shouldn't
leave any signal handlers around in that case - they prevent the object
from being garbage collected, and trigger warnings for accessing proper-
ties of invalidated GObjects.

The _sync function for Message only updates the close button visibility,

Throw an error using an informative message in case a mode uses a stylesheet
that can't be loaded, instead of crashing later because the theming can't be
properly computed, and thus the minimum size of the actors.
(cherry picked from commit 30cb2127a1)
We currently assign the stylesheet to an extension whenever the file exists,
regardless of whether it actually loaded successfully or not.
And thus we load an extension that ships a stylesheet even if that file can't
be used.
There is no point in trying to load an extension if its stylesheet wasn't
loaded in the first place, so make sure this happens only on success.

`NMConnectionDevice._sync()` is responsible for setting up the active
connection that we'll end up displaying. It expects the active
connection to already be in a map `_connectionItems`. If it isn't in
there, we get a null dereference and the indicator can get into a weird
state where it doesn't display devices / connections properly.
Let's change this expectation. If there is an active connection,
`_deviceAdded()` will eventually get to it and call `_sync()` to set up
the active connection state. We make `_sync()` tolerate there being no
active connection when it's called.

To be able to read the properties of the title correctly during the
first relayout of the overlay, the title, just like the border, can't be
hidden. Otherwise the title can be misaligned some pixels to the left
sometimes.
This slighty worsens the issue that windows moved to a separate
workspace using DND will show an overlay when the workspace is shown in
the overview even though no window is pointed at. Before this commit,
only the border would be visible for windows moved to another workspace,
now the title also is.
Avoid setting the width of the overlay title ourselves to keep the
default width of -1, this way StLabel will change its width by itself as
soon as the text is updated.
The width only needs to be changed if the window title changes, and we
don't animate it in this case anyway so there's no need to pass a width
to _animateOverlayActor().
Setting the title width to the preferred width on relayout is impossible
because get_preferred_width() will always return the width we set the
label to before. If the width is not set to -1, there's no way to get
the new preferred width without calculating it ourselves from the
underlying ClutterText instance.

Ensure that the search provider operations (just getResultMetas requests
in the current implementation) in progress are properly cancelled when we
clear the UI, otherwise returned results might still be added when not
needed.
This is triggered for each provider by the SearchResults reset.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/205
Currently when the overview is hidden, any pending search is kept alive,
not only at remote search provider level (as per issue #183), but even
the shell providers proxies continue to get and process data. This happens
even if this is not needed anymore, while the UI reset is performed only
next time that the overview is shown (causing some more computation
presentation time).
In order to stop this to happen, when the overview is hidden, we have to
unset the search entry to an empty value as this would make SearchResults
to have empty terms list and that would make the proxies cancellable to
be triggered (without causing any further search to start).

The object manager tries to synthesize interface removal
events if the bus name of a remote object drops off the bus.
The code had bad typos in it, though: it reuses the `i`
index variable in its inner loop, where it should be using
the `j` index variable.
This commit corrects the i/j confusion.
The object manager tries to synthesize interface removal
events if the bus name of a remote object drops off the bus.
The code has a bad typo in it, though: it confuses `objectPaths`
(the list of all object paths) and `objectPath` (the object
currently being processed this iteration of the loop).
That leads to a failure to synthesize the interface removal
events, and spew in the log.
This commit corrects the objectPath/objectPaths confusion.

The actor allocation doesn't change per-se, but apply_transform()

(cherry picked from commit ab4c72d758)
The default get_paint_volume() implementation will do the union
of children, and the child ClutterText paint volume may expand
beyond StEntry size when text overflows.
We actually want all content to be clipped to the StEntry, so
implement get_paint_volume() and tell it so.

And constrain it in StScrollView instead (instead of falling back to an
infinite paint volume, as the actor as paint/pick impls, but no
corresponding get_paint_volume one).
Fixes artifacts with the AppView (and possibly other places) when paint
volumes are aggressively cached.

When a dialog is added to a window while the overview is shown, we get
its parent using get_transient_for() so we can add it to the right
window clone.
If we have multiple layers of dialogs we have to do this recursively
until we find the root ancestor. This case currently results in an
infinite loop: Since parent is always set to the same window, the
while-condition will always be true.

We show a cover pane on top of the overview during transitions to
prevent issues caused by clicks and mouseover events when the overview
is not ready. Right now, this pane is only being shown on the primary
monitor, which obviosly allows interactions to happen before the
animations are finished on the secondary monitors.
To fix this, use the size of the whole stage for the cover pane.

Instead of consuming the event in front of the input method. Enter
is sometimes overriden by those, so it seems better to let the IM
handle the key event, and react later to it if it got propagated
anyway. That is what ::activate does, so use this signal.
This used to work before ClutterInputMethod/InputFocus because the
IM received the events directly from stage captured events. This
is not the case anymore.

Key events involved in a keyboard shortcut are not completely consumed by
Mutter. That means that if the popupMenu is bound to a shortcut (e.g.

delivered to the popupMenu. We can workaround this issue filtering out all the
events where a a modifier is down (except capslock).
