Separate this logic from _switchWorkspaceBegin() and ensure it is set
before this call. The SwipeTracker code uses the orientation to determine
whether the gesture should begin at all, so changing the orientation on
gesture begin was a bit too late.
But also, that meant the SwipeTracker was left at the default orientation,
which was vertical (unlike workspaces, and like the overview gesture).
This made both swipe trackers try to handle the same swipe, with the
WorkspacesView being doubly unfortunate (for triggering in the first place,
and for happening after the other gesture did queue relayouts on it).
Taking this logic outside of _switchWorkspaceBegin() and having the right
orientation beforehand results in both gestures looking for their direction,
and not meddle with each other.

Calling startTouchGesture() on the workspacesViews can change the
visibility of the workspaces if not all of them are already shown, such
as when there are more than 3 workspaces or for 3 workspaces if we are
not on the central one. This invalidates the allocation and the width
used as distance for the gesture would become 0, resulting in drag
gestures immediately jumping to the first or last workspace due to a
division by 0.

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.

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
allows removing the parent opacity hack in place, which will be done by the
next commit.

Remove Workspace.zoomTo/FromOverview(), they're unused now. Rename
everything up to ControlsManager to prepareToEnter/LeaveOverview(),
since these classes don't run the animation anymore.

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.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1624>
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.
This commit also effectively reverts b64103efc.

As per the latest mockups, then horizontally snapping, the active
workspace should be highlighted. Because WorkspacesView clips to
allocation, we cannot simply scale up the active one. Instead,
scale down the inactive ones.

Synchronizing the actual geometry while animating from / to the overview can
break the animation. Let's prevent that. This code will go away soon anyway,
but to not lose bisectability, it's better not to leave it misbehaving until
then.

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
now we need tighter control of the workspaces positions in allocation,
in order to properly interpolate them.
Move the translation of workspaces to the allocation code itself, and
remove the extra translation step.

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.

Move the background to the Workspace class by introducing a new container

WokspacesDisplay simply remaps the scroll direction into the next
workspace, but that doesn't account for the new horizontal layout.
Scroll horizontally on horizontal layouts when scroll direction is
on the vertical axis.

The scroll adjustment's upper value corresponds to the number of
workspaces, not to the last workspace index. We want the latter
when mirroring the layout in RTL locales, so subtract 1.

Even if they're in the end of the list. So far we've managed to not be affected
by this bug because until GNOME 3.38, workspaces didn't have a background, and
there was no way to navigate to these leftover workspaces, but with the proposed
overview changes for GNOME 40 it'll be very much visible.

When handling all scroll directions, it is imperative to ignore emulated
events. Otherwise we may get the wrong scroll direction, e.g. when natural
scrolling is enabled.
Ignore pointer emulated events in WorkspaceDisplay._onScroll().

Updating scroll position may have significant side effects, e.g.
switching workspace; this should never happen during allocation, as
we're in the middle of painting a frame. So, put it in an idle callback
if we're doing it from an allocation to have the side effects happen the
right time.

Clutter nowadays omits reallocations when only the stage position
changed, that is when the allocation relative to the parent changed.
As a result (apart from better performance of course), workspaces
in the overview may now end up with an outdated "actual geometry"
in case the overview moved to a new primary monitor (of equal size
as the previous one).
Work around that by emitting a signal from the overview on allocation
changes, and use that to update the cached geometry.
We can revert that change once workspaces become part of the regular
overview hierarchy.

This was missed in commit 96f63b08c2 when splitting the combined
layout+scrolling method into allocation and translation.
Add it back to prevent windows from other windows leaking into view
during the transition.

We couldn't clip workspaces views during the overview transition
when we used the "porthole" approach, but as view's allocation
now always matches the expected visible area, we can just apply
the clip unconditionally.

In commit 9297d87775 we stopped syncing the primary view's actual
geometry at the start of the transition when doing a fade animation,
however the view animation may still be triggered by an allocation
change.
Prevent those unwanted size changes during fade by keeping track of
the fade state and explicitly skip syncing the geometry while a fade
is ongoing.
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2969
Since commit af543daf1c, we skip the overview transition when the
actual geometry hasn't been set yet. However with the new layout
manager, the only bit that still needs the separate geometry is
the transition of the view, the workspaces can do their transition
just fine.

When dragging the workspaces through the swipe gesture, all
workspaces must be visible. WorkspacesView's _updateVisibility()
method special-cases this and ensures that.
However, this method is only called when (1) going to the active
workspace, and (2) when the gesture ends. That means, if there
is any workspace hidden by the time a gesture starts, it is never
shown!
Call _updateVisibility() on startTouchGesture() as well.

When going straight to the app picker, we fade in the overview instead
of doing the full-blown zoom transition. In order to keep windows at
their floating position, we must apply the same to the view itself
and not transition to the overview geometry when fading.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1353
We don't always want to sync the geometry when entering the overview,
namely when the fade transition is used.
However we do want the correct geometry once we have entered the overview,
so that workspaces are at their place when switching from the app picker.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1353
Non-primary views always use their monitor's work area for their
geometry, so there's nothing to animate when leaving the overview.
The animation is already limited to the primary view when entering
the overview, so this is also more consistent.

The transition was temporarily removed when switching to the new
workspace layout manager. Now everything is in place to reimplement
it with a combination of the layout manager's state adjustment and
the view's allocation.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1345
So far we've been allocating workspaces in a stack, and relied on
translation to move them to the right position. And as the position
depends on both the workspace's index and the view's viewport, some
care is needed to prevent gestures/scrolling from interfering with
layout updates.
Clean that up by properly allocating workspaces in a row or column,
and use a translation to reflect the current scroll position.
