This new ClutterOffscreenEffect vastly simplyfies subclasses
by allowing them to hand the parent class a CoglPipeline to
use.
Override the create_pipeline() vfunc and return the (cached)
pipeline. Remove the paint_target() override and the now
unnecessary texture size fields from the structure.

Port the blur effect to the new ClutterEffect.paint_node() vfunc.
Update the function names to match what they do, e.g. "apply_blur()"
now creates the blur subtree and thus was appropriately renamed to
"create_blur_nodes()".
There are 3 subtrees that can be generated by the blur effect:
1. Actor mode (full subtree; no cache)
Root
|----------------------------
| |
Layer (brightness) Pipeline
| (final result)
Layer (horizontal blur)
|
Layer (vertical blur)
|
Layer (actor)
|
Transform (downscale)
|

2. Actor mode (partial subtree; cached contents)
Root
|
Pipeline
(final result)
3. Background mode

Now that we can always associate a GIcon with the app, add a method
to access it. While create_icon_texture() is still likely to be more
convenient in most cases, exposing the icon can still be useful, for
example to add it to a different kind of actor or to compare it with
other GIcons.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1342
We still load the surface into an StImageContent, but instead of
adding the content to an actor we hand out, return the content
itself (as GIcon).
That means we lose the ability to specify an icon size, but as we
get the pixel data from a fixed-size surface anyway, that shouldn't
matter much in practice.
Not to mention that the function is only used for fallback X11 icons,
which are already shit more often than not.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1342
On the one hand, this is a bit of a stretch: StImageContent is what
we create from GIcons.
But on the other hand, there's some justification: StImageContent does
represent an image (and likely icon) after all, and there's some
precedent with GdkPixbuf.
In the end as we don't care about serialization or loading from other
API, we can go with a very crude implementation that allows us to
pass out a content as GIcon and use it directly when "loading" it.
We will use that soon to represent X11 window icons as GIcons, which
in turn will allow us to unify app icon handling.

ClutterActor provides the same function, but with a different return
value. So since we already switched to the ClutterActor implementation
in our C code, we can now safely remove st_widget_get_resource_scale()
and update the JS code that's still using the old API.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1287
Instead of using the "notify::resource-scale" signal and StWidgets
"resource-scale-changed" signal, use the new "resource-scale-changed"
signal of ClutterActor, which replaces its "resource-scale" property.
Since we'd now have two "resource-scale-changed" signals, one on
ClutterActor and one on StWidget, remove the StWidget one in favour of
the new one.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1287
The blur effect needs to take the scale-factor into account, so we
listen for scale changes. However we set up the signal handler when
creating a background, which is repeated for each monitor, and every
time the monitor configuration changes. But we only disconnect the
last handler that was connected, and only when we are destroyed,
not when recreating backgrounds.
Fix this by splitting out updating the effect parameters to a separate
method that iterates over all backgrounds, so we can simply set up the
handler from the constructor.

The arrow of the removed app was still left in the list with the
visibility of the arrow still depending on the original list order. This
could either lead to apps with just one window now suddenly having a
down arrow or apps with multiple windows not having one. If the last
window in the list had a down arrow, it would have been displayed
outside the window switcher.

As usually with GObject setters, we should check whether the property
actually changed before setting the value and notifying the property. So
check whether the title or description text actually changed before
setting it.
This fixes a bug which makes the title flicker and change its size,
because when updating the title we remove the "leightweight" css class
and reapply it inside a later, which makes the title appear larger for
one frame.

When scrolled, the container's allocation is smaller than the allocation
of the content. To account for that, commit 2717ca9d08 added the
additional size reported by the layout manager to the content allocation.
However as it did so unconditionally, we now allow children to extend
outside the parent even when *not* scrolled, which breaks any constraints
set on the container (like "width" or "max-height").
Fix this by only extending the child allocation in scrollable dimensions.

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.

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.
