The performance of the icon grid was being hindered by a large number
of primitives (a few hundred) being copied from the CPU to the GPU on
each frame. This was first noticed in mutter#971 but we failed to
investigate all the issues at the time.
You can also see the high number using `COGL_DEBUG=batching` or
`COGL_DEBUG=disable-texturing`. So now it's obvious that high number is
every letter of every label being uploaded as a separate quad. Let's not
do that and instead treat the whole label as a single quad/texture.
Measured performance on an i7-7700 at UHD 3840x2160:
Journal entries per frame on the icon grid:
* Before: 288 (18 KB copied from CPU to GPU)
* After: 73 ( 4 KB copied from CPU to GPU)
Spring animation:
* Before: 20-30 FPS, avg 22/peak 45 milliseconds per frame
* After: 30-40 FPS, avg 14/peak 28 milliseconds per frame
Scrolling the icon grid:
* Before: 15 FPS, 50 milliseconds per frame
* After: 30 FPS, 28 milliseconds per frame

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.

Overview has signals to notify about starting, cancelling, and
finishing icon drags, but none of these signals pass the dragged
item to the callbacks.
Pass the dragged items to the 'item-drag-*' overview signals.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1332
Commit c7e597cf72 tried to improve the slide animations when entering
the overview by using the same time as the overall overview animation,
but in fact broke the animation most of the times.
That is because the Overview imports OverviewControls before defining
the ANIMATION_TIME variable, so any javascript code that is evaluated
during that import will see the value as "undefined" (which is converted
to 0 for the animation).
Fix this by moving the ANIMATION_TIME variable before the imports instead
of the usual placement.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1331
When you tap Super and see the sidebars and windows slide, it looks more
cohesive if those animations complete at the same time.
Previously there were 0.09 seconds difference between the two animations
which was enough to make it look slightly buggy. Now it doesn't.

We now found the underlying bug: The ControlsManager (which causes the
bad call to `_updateWorkspacesFullGeometry()`) is getting (re-)allocated
while we add the view to the overviewGroup actor because the
overviewGroup is already visible and the view is immediately getting
mapped by `clutter_actor_add_child_internal()`. That causes a
resource-scale calculation and that indirectly causes a call to
`_clutter_stage_maybe_relayout()` (explained more detailed in the last
commit).
So now that we got rid of the immediate relayout happening when mapping
the view, we can revert this fix.
This reverts commit 6cc19ee6f0.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1315
When the bounding box size is 0 during allocation (which happens right
after creating a window for example), we're doing a division by zero and
end up with a NaN scale. This ends up making the childBox NaN, which
triggers an error in Clutters allocation machinery.
So fix that and fall back to a scale of 1 in case the bounding box is
empty.

The current microphone indicator only indicates if the microphone is in
use. Users might be also interested if their microphone is recording
or is muted, this commit enables that without opening the pop-up
menu. The microphone icon changes itself, depending on the sensitivity
of the microphone. It behaves similar to the already existing volume
indicator.

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.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1271
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
The new icon grid layout operates based on rows and columns, and
doesn't try to dynamically adapt it to fit to the container. In
this case, it is better to have a pre-defined set of well-known,
well-tested rows and columns, and switch between them based on
the aspect ratio of the screen.
Introduce a set of modes to the icon grid, and select the mode
that is closest to the aspect ratio.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1271
IconGridLayout is a new layout manager that aims to replace the
current paginated layout algorithm implemented by the icon grid.
There are a few outstanding aspects of this new layout manager
that are worth highlighting. IconGridLayout implements all the
mechanisms necessary for a paginated icon grid, but doesn't
implement any policies around it. The reason behind this decision
is that this layout manager will be used by other places (e.g.
the login dialog) that demand different policies to how the
grid should look like.
Another important aspect of this grid is that it does not queue
any relayouts when changing its properties. If a relayout is
required, the actor should manually queue it. This is necessary
to avoid layout loops.
Add the IconGridLayout class. Next commits will do the surgery
to IconGrid and any related code to use this new layout manager.

For drag actors which get reparented to the uiGroup, we currently wait
until the next input event to set the fixed position of the actor, until
that they will just be allocated their old fixed position, which is 0,
0.
So avoid drag actors flickering at the top left for one frame and
position them correctly right after reparenting.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1310
Properly adjust for drag actors which were allocated using a custom
vfunc_allocate() and might not have gotten allocated their preferred
size. When DND reparents the actor to the uiGroup, the drag actor will
get allocated its preferred size, so we also need to take the difference
between the old allocation size and the preferred size into account
before reparenting to the uiGroup.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1310
Properly handle drag actors which are not allocated using a fixed
position and disable the fixed position we were using to move the actor
around before we reparent it again to its original parent.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1310
As the view now scrolls from right-to-left in RTL locales, the
scroll bar handle should reflect that.
Likewise the event handling needs adjusting as well: Scrolling
left should increase the adjustment value, and clicking the
trough to the left of the handle as well.

The workspace.js file is quite large and is a bit confusing when it
comes to the term "window" in there, because it can either refer to a
WindowPreview of a complete window or to an individual window like an
attached dialog.
So try to avoid that confusion and split the new WindowPreview class and
its WindowPreviewLayout layout manager out into a new windowPreview.js
file.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1307
MetaWindow is Mutters representation of a window and provides all the
APIs about it, MetaWindowActor is just the ClutterActor that's drawing
that window. So use a MetaWindow to create a WindowPreview instead of
the window actor.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1307
We want to stop using the MetaWindowActor for things which are actually
related to the MetaWindow, one more thing where we can change that is
the overviewHint, which is currently added to the MetaWindowActor.
So move that hint to the MetaWindow and stop calling
get_compositor_private() in a few more places.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1307
We can simply get the MetaWindowActor by calling
MetaWindow.get_compositor_private(), so stop accessing the realWindow
property of WindowPreview. For this we also have to make _isMyWindow()
and _isOverviewWindow() take a MetaWindow as an argument instead of a
MetaWindowActor.
Since the WorkspacesThumbnails are also drop targets for WindowPreviews
and their WindowClones also have the public metaWindow property, switch
to using the metaWindow property there, too.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1307
Since the WindowPreview class rarely needs to handle the actual actor
painting the window preview, refactor the WindowPreviewLayout a bit to
only pass a MetaWindow to its addWindow() and removeWindow() functions.
Also make the getWindows() function return an array of MetaWindows,
which makes the getMetaWindow() function obsolete, so remove that.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1307
We're going to remove ClutterClones, so call the parameters to
addWindow() and removeWindow() "actor" instead of "clone". Also make the
destroyIds less confusing and rename the actual actor destroy id to
"destroyId", and rename the window actors destroy id to
"windowActorDestroyId".
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1307
Since ClutterClones are going to be removed, let's switch the
terminology here to something that's more understandable and rename the
WindowClone class and its layout manager to
WindowPreview/WindowPreviewLayout.
