Currently, ActivitiesContainer reacts to showAppsButton and
transitions between app grid and window picking states on
its own. In the future, we want full control over this.
ControlsManager already has a state adjustment that represents
all possible overview states. Propagate this adjustment up to
ActivitiesContainer, and use it to drive the transition.
This requires moving the callback to the showAppsButton to
ControlsManager, since now it control the state adjustment
itself, not ActivitiesContainer's adjustment.

In the future, we want to tightly control the state of the
layout throught gestures, which requires hooking everything
together with adjustments. This is the first step in this
direction.
Add a new custom layout manager for ControlsManager that
allocates the search entry, the view selector, and the Dash,
vertically.

Currently, gnome-shell uses the wrong scrolling direction for
horizontal scrolling events.
When dx < 0 for a smooth scroll event, then the scrolling direction is
supposed to be Clutter.ScrollDirection.LEFT, instead of
Clutter.ScrollDirection.RIGHT, as dx is smaller than 0.
Fix this issue by swapping the values LEFT and RIGHT.

It is possible for an initiated session to complete without
a request if polkit can authenticate the action without user
input. We fail to clean up after ourselves in that case, as
the cleanup is done after the dialog is closed.
The dialog can still be shown when the code that hides existing
dialogs while the screen is locked shows it on unlock. But as
the session was closed, the dialog is now defunct and cannot
be dismissed by the user.
Fix this by running the cleanup on close() when the dialog
wasn't shown.

The children variable holds the icons that were originally in
the dash. For the separator visibility, we should consider the
icons that are in the dash after the update, so we must consider
additions as well as removals.

Previously we used a bunch of heuristics for this. We checked if velocity
was directed towards the nearest snap point and its value was larger than
a threshold. If it is, we completed the swipe, otherwise we cancelled it.
This was good enough at the time, because this code was originally written
for back/forward swipe. Since then, the swipe tracker was extended to
handle arbitrary snap points and not just 0 and 1, or -1 and 0, depending
on text direction. After that it was iterated on, but never significantly
redone.
This worked well enough, but had two problems:
1. In some cases, notably overview, it may be wanted to be able to swipe
through multiple pages at once. This wasn't really possible because we
always picked the adjacent snap point.
2. Since we can't do that well, we want to restrict swipes to one page at a
time. It was done in a rather hacky way by clamping the position into
[-1, 1] range from the place where we started the swipe. This works
if we start the swipe from idle position, but if an animation was
already going, the range would be clamped to arbitrary values, and very
likely containing only one snap point, which we already swiped past at
this point. In this case, finishing the swipe would cancel it regardless
of velocity. This means that if one tries to quickly move through
carousel pages via swiping, half of the swipes will be inexplicably
cancelled.
We'll use the deceleration formula from
https://medium.com/@esskeetit/how-uiscrollview-works-e418adc47060#10ce
to calculate then projection point, then pick the nearest snap point and
calculate the duration as we did before. It works well enough for short
distances, but has two problems:
1. It caps the maximum distance at a pretty low value - about 5 pages in my
testing.
2. With how we pick the nearest snap point, it's too easy to accidentally
cancel the swipe,
To combat the first problem, we can modify the curve: only use linear
function at small distances, and smoothly transition it to a parabola
further.
For the second problem we can add two special cases: first, if the swipe
ended up between the initial snap point and the next one, we always prefer
the latter. Second, a good old velocity threshold for cancelling.
We'll also use a slightly smaller deceleration value for touchpad: 0.997
instead of 0.998.
Now that we can pick any snap point, the [-1, 1] clamping doesn't make
sense anymore, so instead let's replace it with a more flexible
mechanism: if we're near a snap point, pick its adjacent snap points.
Otherwise, take the two nearest snap points, and take their adjacent
snap points. This way we have 3 snap points to choose from when
starting a swipe from an idle position, and 4 if we start during an
ongoing transition.
This way, if we've just swiped from snap point n to n+1, the transition
will pick snap points n-1, n, n+1, n+2 and if we swipe again, we will
likely land on n+2. During that transition, if we swipe again, it will
likely have already passed the snap point n+1, so this time the available
snap points will be n, n+1, n+2, n+3, so we can swipe again and it will
still complete, and so on.
This will make it easy to allow multi-page swipes as well, by just
removing the clamping.

In some cases we may get anevent with very low delta at the end of the
swipe. While we can't completely ignore them, we can smooth them using a
scroll history, similarly to what GTK kinetic scrolling does: keep track
of the last 150ms of events, and sum their deltas when calculating the
velocity.
The logic is based on what GTK does in GtkGestureSwipe and
GtkEventControllerScroll.

The reason this wasn't using the Gio.DBus.makeProxyWrapper() convenience API is that it passes custom flags to the proxy, and that wasn't supported by the wrapper at the time.
As this is now possible, this commit migrates us to the new API.

Commit 473e77e2c5 fixed applying the :insensitive pseudo class to
initially unreactive widgets, and adjusted the style test to work
with that.
In hindsight, we can do better than just making the test work, and
include a test case for the :insensitive styling as well (namely
the issue the previous commit was fixing).

Let empty input result in an error, just like other invalid commands
(bad syntax, nonempty whitespace, etc.). GLib already has an error
message “Text was empty (or contained only whitespace)” which it shows
for whitespace-only input, so letting that message apply also to empty
input makes sense.
This requires some tweaks further down the file to avoid interpreting
empty input as an empty path (relative to the home directory) and then
opening the home directory.

We are applying the :insensitive pseudo class to unreactive widgets,
or at least we are supposed to. As we currently only update the style
on notify, we don't apply it to initially unreactive widgets.
This was covered up partially until recently when Clutter started to
use G_PARAM_EXPLICIT_NOTIFY. Before that, the notify handler would run
when explicitly setting :reactive to FALSE at construction time.
Make sure we always apply the pseudo class correctly by updating it
after construct properties have been set.

We want to use the fast path of filling the entire area if either the
left and right shadows would overlap or the top and bottom shadows. The
latter check was wrong due to a typo resulting in the regular path
being used in some cases it couldn't (and shouldn't) handle.
This was causing the inset shadow used to highlight panel buttons to
not appear for buttons above a certain width.
