As per design discussion, the first page is a somewhat of a special
page where we really don't want to change anything unless necessary.
Append new icons at the first available slot after the first page.
Make the placeholder icon be appended to the first available page
as well, since it's always used when dragging from folder dialogs.

When the app folder dialog handles a drag hover, it starts a timeout
to popdown if dragging outside the "real" dialog area. However, when
dragging inside it, BaseAppView handles all drag hover events which
would disarm the popdown timeout. In cases like this, it's almost
impossible to prevent the timeout from triggering, which always pops
down the dialog.
Add a drag monitor when handling any drag hover (which only happens
when dragging outside the folder's icon grid); and eventually disarm
the popdown timeout from the monitor's motion event. Remove the drag
monitor when dragging over the folder dialog again.

App folders are now customizable, and the way to move icons to
another page is by throwing the cursor to either the left or
the right of the grid.
However, doing that triggers the popdown timeout, wich is 600ms
as of now, which is considerably short for such interaction.
Increase this timeout to 1.5 seconds.

Now that the DnD code is shared between AppDisplay and
FolderView, we hit an unexpected problem: FolderView is
handling drag events even when the folder dialog is hidden.
As a side effect, this spams the journal with warnings.
Only handle drag events when mapped. On unmap, disable
the view's drag monitor, and disconnect from all drag
events.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1284
This code will be shared with FolderView in the next commit, so
avoid duplication already and move the to-be-shared code into the
base class.
Because BaseAppView can handle vertical and horizontal orientations,
adapt the drag overshoot code to also handle horizontal overshoot.

When redisplaying, we currently only remove and add icons, but
never adjust the position of already added icons. If the icon
position changed, it wouldn't be reflected on the icon grid.
Make sure to move already added icons.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1284
It is important that '_loadApps()' return a sorted list -- adding the
same icons at the same positions but in different orders results in
a wrong icon grid.
Add support for using a custom positioning function, and implement it
in AppDisplay. Because FolderView doesn't implement a custom sorting
function, the items are still sorted alphabetically.

The leeways are parts of the icon that ignore incoming drag
events. This is how IconGrid and IconGridLayout treat it, and
this is how the icons should treat themselves too.
Make AppIcon ignore dragging over the left and right leeways.

Noticed while working on customizable folders. Calling GrabHelper.ungrab()
ends up calling FolderDialog.popdown(), but at this point the '_isOpen'
field isn't updated yet, so we end up calling popdown() twice.
Update the '_isOpen' field before ungrabbing.

In the past, the icon grid would update the number of pages
during the call to adaptToSize(). However, after the new grid
layout landed, the number of pages is updated by the time an
item is added or removed.
Instead of comparing the old and new number of pages in the
icon grid, compare the pages shown by the indicator, and the
grid pages.

Now that we don't have the Frequent tab anymore, and subsequently
the buttons to switch tabs, the app grid fill all the way to the
bottom, leaving no room for drag overshoot.
Add a 20px (i.e. OVERSHOOT_THRESHOLD) area at the bottom of the
grid where dragging actually scrolls to the next page.

The two BaseAppView subclasses now share a lot in terms of
widgetry: they both have a scroll view, pagination dots, swipe
management, etc.
Move this shared code into BaseAppView. Notice, however, that
BaseAppView only creates the widgetry, but it doesn't add them
to any specific layout. FolderView arranges the widgetry in a
vertical box, while AppDisplay arranges it in a ShellStack.
Add a new 'orientation' parameter to BaseAppView and use it
to determine the orientation of the pagination dots, the swipe
tracker direction, and the scroll event handling.
It is worth noticing that the scroll event is a bit more
sophisticated now: when the orientation is horizontal, it
handles all directions since mice wheels usually only generate
up/down events.

When FolderIcon is destroyed, it destroyed the FolderView and, if
there's a folder dialog present, it destroys the dialog as well.
Turns out, the folder dialog adds the icon's FolderView to itself.
The view becomes part of the dialog's actor tree. When the dialog
is destroyed, it also tries to destroy the view - but the folder
view was already destroyed by FolderIcon!
Fix that by letting the dialog destroy the folder view if it exists,
otherwise destroy the folder view directly.

Add app icons to the exact page and position they're located
instead of always appending. This will be useful later when
custom icon positions are in place.
For now, it assumes pages are always filled, which is true,
but this will also change with custom icon positions.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1271
AppDisplay currently adds all icons, and hides the ones inside
a folder. Change that to only add the icons that are not inside
folders. Adding an icon to a folder removes the icon from the
main grid.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1271
When filtering out the app icons, AppDisplay calls FolderIcon.getAppIds(),
which then calls FolderView.getAllItems(). This last function reads the
already added app icons inside the given folder, and return their app ids.
So far, so good.
When the GSettings backing a folder changes, FolderIcon emits 'apps-changed'
to notify AppDisplay that the folder changed.
Cool.
When AppDisplay receives this signal, it first recreates its own icons, then
updates the folders, and finally hides the icons that are inside folders.
This series of events is unfortunate. Future patches will need the folder
to be updated *before* AppDisplay updates its own icons.
Update folder icons before chaining up to BaseAppView._redisplay().
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1271
The icon grid is always paginated, so the app grid code doesn't need
to behave differently in the FolderView and AppDisplay.
Move the keyboard handling to IconGrid itself, and remove the now dead
code from AppDisplay.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1271
Now that the folder dialog covers the whole primary
monitor, it eats all input events, and doesn't allow
the event blocker to detect clicks.
Move the click action to the folder dialog itself, and
popdown the dialog if a click is triggered on the dialog
(but not on any children).
