The behavior of workspaces is different depending on whether
the overview is in window picker state, or app grid state.
When in window picker state, clicking on adjacent workspaces
should only activate them, without hiding the overview; and
clicking on the active workspace hides the overview. When in
app grid state, clicking on a workspace must always hide the
overview.
Pass the overview adjustment to Workspace, and leave overview
if the overview state is bigger than WINDOW_PICKER.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1645>
The overview transition consists of getting the initial and final
states of the overview adjustment, derivating various other internal
states from them (such as the fit mode, opacities, translations, etc),
and finally interpolating the allocation boxes.
When interpolating between the fit mode, WorkspacesView uses the current
allocation box to derivate the SINGLE and ALL fit mode boxes. However,
that creates a curved path during overview transitions. What we really
want to do here is calculate the fit mode box relative to the corresponding
overview state. For example:
+----------------+----------+------------------------+
| Overview State | Fit Mode | Workspaces geometry |
+----------------+----------+------------------------+
| HIDDEN | SINGLE | Cover entire screen |
| WINDOW PICKER | SINGLE | Between minimap & Dash |
| APP GRID | ALL | 15% screen height |
+----------------+----------+------------------------+
Using the table above as the reference, when the overview transitions
between WINDOW PICKER and APP GRID, we must interpolate between
(SINGLE fit mode @ between minimap & Dash) and (ALL fit mode @ 15% screen
height). That way, we always interpolate the final boxes, which corrects
the odd path that workspaces follow during this transition.
Make the WorkspacesView of the primary monitor use these cached boxes
when the overview is in the middle of a transition, and the fit modes of
the initial and final state differ, to calculate the workspaces positions.

It makes more sense in a spatial overview that the app grid
comes and goes to somewhere in the screen, instead of fading

Move AppDisplay, WorkspacesDisplay, and ThumbnailsBox from ViewSelector to
ControlsManager. This allows to always allocate the correct size for AppDisplay,
and will enable for a plethora of further improvements. The end goal is to
completely remove ViewSelector, and let ControlsManager handle the layout of
everything that's visible in the overview.
For now, replace the apps page with a dummy actor in ViewSelector.
Adjust various callers around the codebase to not access the ViewSelector
directly from the overview anymore.
Bind the opacity of the primary workspace to WorkspaceDisplay's opacity. This

Now that Overview is able to ease into any state, be it window
picker or app grid, we can move this ViewSelector method to
Overview itself, which is its rightful place to live.

WorkspacesView uses the floating layout when the overview is in window
picker mode, and the session layout when the overview is in app grid
mode. Up until now, the fit mode adjustment was used to derive the
workspace mode, but it is incomplete as it doesn't have the full range
of workspace states.
Make ViewSelector cascade the overview adjustment to WorkspacesDisplay,
and use the overview adjustment itself to derive the workspace mode.
Extra workspaces don't have to account for the fit mode, and thus are
basically a clamp(state, 0, 1) of the overview state. However, don't
call animateTo/FromOverview() anymore, since they ease the workspace
mode adjustment.

Boy, does this commit feel good.
While the workspaces view on the primary monitor *appears* as part of
the overall overview hierarchy, this hasn't actually been the case
until now. We synchronized its size and (stage) position to match
the workspaces display, but actually kept in a separate layer for
the transitions to and from the overview.
But now that the new layout manager slides out completely during the
overview transitions, the workspaces display starts out covering the
entire work area, which is exactly what we need for the transition.
So finally stop faking it, and actually make the primary workspaces
view a child of the workspaces display.

Instead of delegating it to ViewSelector, make the transition to and from
overview ease the main state adjustment.
This commit temporarily breaks these animations, but on the other hand
introduces an important feature: ViewSelector is always allocated to the
actual size. This will finally allow for adding WorkspacesView as a child
of WorkspacesDisplay, and finally remove the actual geometry hack, which
is what next commit is about.

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.

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

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.

wasn't shown.

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.

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.

The code to update the actor position based on the cursor and current
scale was run in a 'new-frame' handler. This is working fine when
animations are enabled, but when they are turned off this does not work.
This is because the 'new-frame' signal is emitted before the changes for
that frame are applied. So with animations off the position was only
ever updated with the starting values. As a result the shrunk actor was
not being dragged by the position where it was clicked, but by where it
was clicked in the original size, which is likely not even on the shrunk
actor.
This change now also updates the position in the onComplete handler
which gets run with the final scale, even if the duration is 0.

When vertically snapping, WorkspacesView currently allocates workspaces
side-by-side, then applies an extra step of translation to center to
the active workspace. This extra step, however, gets in our way because

in order to properly interpolate them.

Currently, WorkspacesView positions each workspace on a
per-page layout, each page with the allocated width and
height of WorkspaceView. This layout doesn't work well
with horizontal workspaces.
Layout workspaces side by side, instead of per page. The
layout is influenced by a "fit mode", which reflects the
different behaviors exposed in the mockup. This fit mode
represents whether a single or all workspaces will fit
available geometry.
The single fit mode is always used for now. Next commits
will make it switch to the all fit mode when in the app
grid state.
The translation_{x,y} also needed to reflect the switch to
a side-by-side layout, and use the geometry of the workspaces
to determine the offset. Notice that, when the fit mode is ALL,
there's no translation applied.

The new window preview overlay requires getting the app icon for a
window from the window tracker when it gets initialized. The window
tracker listens for the same 'window-added' signal on the MetaWorkspace
that the gnome-shell Workspace listens for to add the window preview.
The window tracker however reconnects all its signal handlers whenever
the number of workspaces changes, which means that its signal handlers
get called after the ones in Workspace ones. So by the time the
'window-added' handler in Workspace is called, the window tracker does
not have an app associated with the window.
To fix this ensure that all window related signal handlers in Workspace
are run after the ones in the window tracker.

is the same between all screens. Clip all animations to their screens so
that the windows don't leak to other screens.

Currently, the workspace swipe transition only has one workspace in each
direction. This works until you try to do multiple swipes in quick
succession. The second swipe would continue the existing transition, which
only has 2 or 3 workspaces in it, and will hit a wall.
To prevent this, take all workspaces and arrange them into a column or row,
depending on the layout, and use that as a transition.
For the transition that happens when focusing a window on another workspace
(for example, via Alt+Tab), still use only two workspaces instead of all of
them.
Since we don't support layouts other than single rows/columns anymore,
diagonal transitions aren't supported anymore, and will be shown as
horizontal or vertical instead.
Since nw alt-tab and gesture transitions are different, don't allow to do
both at once, that is, disable swipe tracker when a programmatic transition
is going. This will also conveniently cancel a gesture transition if a
programmatic one is initiated while a gesture is in progress.
