These traditionally got the various ClutterEvent subtype structs as their
argument, so it was not allowed to use ClutterEvent generic getter methods
in these vfuncs. These methods used direct access to struct fields instead.
This got spoiled with the move to make ClutterEvent opaque types, since
these are no longer public structs so GNOME Shell most silently failed to
fetch the expected values from event fields. But since they are not
ClutterEvents either, the getters could not be used on them.
Mutter is changing so that these vmethods all contain an alias to the
one and only Clutter.Event type, thus lifting those barriers, and making
it possible to use the ClutterEvent methods in these vfuncs.

The FolderView is a subclass of BaseAppView, which already has a
full-blown SwipeTracker attached to it. So no need to add another
PanGesture on top, the SwipeTracker will handle it for us.

This behavior makes more sense to have in the iconGrid itself: When a
page is filled up with items, the new item should never go to the start
of the next page, but always to next empty slot.

Folders reflow across pages because they don't set
allow_incomplete_pages to true. This means we want the nudging of items
to happen slightly differently when dragging an item across pages:
- When dragging from lower page index to a higher one, always reflow
towards the start of the grid (because there's now an empty slot on the
old page and items on the new page will force-reflow towards that)
- When dragging from a higher page index to a lower one, we can reflow to
the end as we usually do
To archive this, factor out the selection of "reflow direction" into a
separate variable that always defaults to "end" (because empty space is
always at the end of the grid). Set it to "start" when the item created an
empty slot on the current page or (and this is new:) on a previous page in
the folder case.

The iconGrid's getDropTarget() API supports dropping items to adjacent
pages just fine, but in the AppDisplay, we clip the grid and don't show
those adjacent pages. That doesn't stop getDropTarget() from picking
drop targets which are on adjacent pages though, so we need to filter
those out in the layer above.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2348>
Returning a page and a position for the drop target seems more
straightforward than returning an actual grid item in getDropTarget().
With the next commit, this will allow us to throw away drop targets that
are not on the current page.

_getLinearPosition() is a function that converts a page and position
index to the "accumulated" index that includes all pages before the
page. The function is used by _addItem() and _moveItem() for getting the
new index of an item inside the _orderedItems array.
Now when passing -1 as position to _addItem() or _moveItem(), this means
the item should be appended to the page. Right now _getLinearPosition()
returns the last item index on the page when passed -1, inserting the
item into _orderedItems at this index will actually not append it, but
insert it between the second last and last item.
To fix it, let's make the whole thing more robust by explicitly passing
an item to _getLinearPosition(). This means we simply no longer have to
assume what "-1" means. Moving the call to _getLinearPosition() to
happen after addItem() and moveItem() ensures that the new item position
is used and not the old one.
This fixes issues where the _orderedItems array gets out of order when
moving or adding items.

Dropping a icon from the dash to the application grid will set this._placeholder
to null. However the AppIcon is still used to represent the application in the
application grid. If we click on it we emit a pressed event. Stop assuming
that this._placeholder is still valid in the callback, use the icon parameter
instead.
This fixes the following error:

In addition to the "overshoot/bumping into monitor edge" behavior we already
have, we also want to switch pages when simply hovering above the prev/next
page indicators.
This page switch shouldn't happen immediately though, it needs to be kicked
off using a timeout instead. The reason for that is that the next/prev page
indicators are large areas, and simply dragging there isn't enough of a
gesture to really interpret as "the user wants to switch pages".
After this page switch has been toggled once, it can be repeated using the
same "repeat" timeout we introduced with the last commit.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2581>
Right now we have a behavior in the appGrid where "bumping" the cursor
against the monitor edge during DND switches the page immediately, and
holding it there (at the monitor edge) switches pages again after a timeout.
With the next commit we'll introduce another way of switching pages during
DND, that is hovering over the next/prev page indicator to switch pages. To
allow those two methods to play well together, refactor the "overshoot" page
switching to make the timeout into a more generic "repeat" timeout. This
means we can now divide page switching can be roughly divided into two
different steps:
- Switch page immediately when bumping cursor against screen edge, also
works when repeatedly "bumping"
- Switch page automatically again after a second when keeping the cursor at
the screen edge without moving
We'll reuse the "repeat" timeout that's introduced here in the next commit,
where we'll introduce page switching by hovering the next/prev indicators.

With MR https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2335,
the page navigation in the app grid was redone and prominent, always visible
navigation arrows were added. This larger change in the navigation of the
app grid also involved changes to the drag and drop behavior.
Before those changes (in GNOME 42), switching pages during DND in the app
grid worked like this: By "bumping" the cursor against the monitor/appGrid
edge, an immediate page switch would be triggered. Leaving the cursor in
that edge area would then trigger repeated page switches every second. By
repeating the "bump" gesture (moving cursor back into the grid, then
"bumping" against the edge again), it was possible to switch pages even
faster than every second.
When adding the always visible navigation arrows, we briefly tried out a
different way of page-switching during DND with commit 09b975fa: The "bump
against monitor edge" gesture (or "overshoot" behavior as it's called in the
code) was replaced with a hover timeout on the navigation arrows. The idea
behind that was to allow hovering the navigation arrow during DND to
eventually trigger a page switch, which also makes sense.
The replacement of the "overshoot" behavior made some people unhappy though,
so it was decided to bring back the old "overshoot" behavior with commit
4dcae8dd. Due to time pressure before the release that didn't go very well
and we ended up with a mixup of both approaches that doesn't feel too
polished.
So let's try to fix that by first going back to the working "overshoot"
implementation as it was in 42, then slightly refactoring that
implementation, to finally incorporate the new "page indicator hover"
behavior that https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2335
originally intended to use.
This reverts commit 4dcae8ddd2.

When the overview is hidden just after starting GNOME Shell the app
grid is not populated yet. Thus, this._grid.nPages is 0. When the
overview is about to be hidden, we call goToPage(0) on the AppGrid.
This results in pageNumber being clamped to -1 and leads to the
following exception:

This brings back the ability to drop an icon beyong the last page.
Because the acceptDrop() method does not have access to the target
drop actor, to avoid an extra pick or manually calculating it from
allocations, simply store it during DragMonitor.dragDrop(), and
use the target actor in acceptDrop().
This commit also removes the last usage of SidePages, so drop the
enum too.

This is a major departure to how page previews used to work. Add
a new layout manager that handles showing and hiding page previews
and navigation arrows. Move most of the code handling page previews
to this new layout manager.
The layout manager allocates at most 20% of the screen width for
the previews, and at least the width of the arrow.

this commit, but will be reintroduced in later commits.

Back in the day, adaptToSize() contained mad maths to figure out
icon sizes. Over time, its scope was reduced, to the point where
we are today where it mostly just redoes some quick maths to
predict the grid size based on the CSS box model.
Remove adaptToSize() from BaseAppView and child classes. It still
is an internal detail of the IconGrid class, but it's not exposed
as a "public" method anymore.
This removal is not perfect, as it doesn't move or compensate for
any of page indicators and arrows code. This will be done in follow
up commits introducing a new layout manager for that.

Our search provider API has to be asynchronous to support remote

The swipeTracker wants the distance between two pages passed to it in
confirmSwipe(). In case of the app grid, the correct distance is not the
size of the scrollView (which has the width of the whole screen), but
instead the allocation size of the iconGrid (which is the actual size
of a page in the grid).
So pass the allocation size of the iconGrid to the swipeTracker, this
makes sure the pages move perfectly in sync with the pointer when
dragging using the mouse or touchscreen.

Creating these default folders still doesn't work. After some
investigation I found that's because the template we use for
the path when creating the `child` `Gio.Settings` instance
results in a double slash - it comes out as e.g.
/org/gnome/desktop/app-folders//folders/Utilities/ . dconf does
not gracefully handle this as many other things that handle
paths do, it considers it a programmer error. It results in
error messages like:
dconf_changeset_set: assertion 'dconf_is_path (path, NULL)' failed
which is slightly confusing. Anyway, we fix it by removing a
slash from the template.
