Window previews can spill out of the container when their position in the
session overflows the monitor boundaries. In the past, Workspace didn't have
a visible background, and was (almost) always fullscreen, which would mask
this particular problem. However, nowadays, it is very much noticeable when
this situation happens.
Clip the window previews container to its allocation when the overview state
is bigger than WINDOW_PICKER. That is, between HIDDEN and WINDOW_PICKER states,
inclusive, no clipping is applied.

Instead of adding it to the window previews container, add it to Workspace
itself. This requires expanding WorkspaceBackground, so add the relevant
x and y expand flags.
Since the background is beneath the window previews, create and add it before
the window preview container.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1691>
Currently, Workspace is a single actor that contains both the background,
and all window previews, and is managed by WorkspaceLayout. In the future,
this concentrating aspect of it will bite us; we want the window previews
to be clipped to the allocation, but not the background, since it will
have shadows.
Make Workspace subclass St.Widget with a ClutterBinLayout as layout manager,
and move window previews to a child actor. To reduce the impact of this
extra actor, it's a ClutterActor instead of a StWidget, and the spacing is
still set on Workspace itself.

The WorkspaceBackground class has specific code to clip the background
to the workarea. However, it doesn't monitor for workarea changes, which
means it cannot react after being created.
Connect to 'workareas-changed', and update the workarea, the radius bounds,
and relayout when workareas change.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1691>
The primary workspace is displayed in the overview, and clipping it
ends up clipping the shadows too. Since Overview's ControlsManager
itself clips to allocation, no windows in the primary monitor spill
to other monitors. However, not clipping non-primary monitors might
end up in situations where their windows spill into the primary one.
Make sure to only clip workspace views of non-primary monitors.

The dialog is shown at session start, which right now means in the
regular session, however the plan is to start the session in the
overview. When that happens, the "Take the Tour" button should get
the user to the Tour without additonal actions.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1699>
Right now the rowSpacing and columSpacing of the layout strategy is
calculated by looking at the overlapping sizes of the close button and
the app icon of the WindowPreview, plus a constant spacing read from CSS
by the WorkspaceLayout that's added to that. We're not factoring in the
extra size of the scaled-up WindowPreviews here and instead depend on
the constant spacing being large enough. If we don't want to depend on
the spacing here, we should add the scaled-up extra size to the sizes
returned by chromeWidths() and chromeHeights().
Since the last commits all previews scale up by the same amount of
pixels, so we can now just add that size to the values returned by
chromeWidths() and chromeHeights().
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1692>
Scaling differently sized WindowPreviews by a constant factor will
result in smaller windows getting enlarged by a smaller amount of pixels
than larger windows (1000*1.02=1020 but 100*1.02=102, one will grow by
20 pixels and the other one by 2), this can look a bit weird because
smaller windows don't scale up as much as larger windows.
So introduce a constant extra size to use when scaling windows up, we
set only the half size there because we want to ensure that the size
added on both sides is not fractional and we remain aligned to the pixel
grid.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1692>
Right now the spacing between icon and title works using a little trick
that doesn't really seem intended: The title is offset by
(icon-height * ICON_OVERLAP), when the icon is actually overlapping the
preview by ICON_OVERLAP, and *overflowing* the preview by
(1 - ICON_OVERLAP).
So correct that and offset the title by
(icon-height * (1 - ICON_OVERLAP)), and since now there's no spacing
anymore, add a proper ICON_TITLE_SPACING to that offset.
Also add the new ICON_TITLE_SPACING to the overlapHeight, where the
spacing was ignored so far.

The scale property tracks the relative size at which we display thumbnails
given the space we have available.
That assumes that the allocation represents that available space, but it will
actually be smaller while the minimap itself is collapsing.
Luckily we have an easy option to avoid a distorted scale: Just don't update
it while collapsing. We expect scale changes when adding or removing thumbnails,
but as we freeze those during transitions, we can do the same with the scale.
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/3739
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1696>
Right now the minimap only hides itself in case of a single static
workspace. That's not only an edge case, but also not expected to
change while the overview is visible, so changing the visibility
without a transition is fine.
However that is about to change, and we'll hide the minimap as well
when there are fewer than three workspaces. As that condition is
very much expected to change from within the overview, the transition
should be animated.
Implement that via a new :collapse-fraction property on ThumbnailsBox,
and use that to transition both the height of the box itself and the
scale of the individual thumbnails.

Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1696>
We currently have two components that show or hide the minimap:
- the thumbnails hide themselves in case of a single static workspace
- overview controls show the minimap when no search is active
That obviously doesn't work correctly.
To fix this, change thumbnails to set a new :should-show property instead
of the visibility, and let the overview controls take it into account
when changing the visibility.

As planned and shown in the mockups for GNOME 40, round the corners of
the background wallpaper of workspaces.
To do that we use the new rounded-clipping support of
MetaBackgroundContent and we animate the radius by attaching it to the
stateAdjustment just like everything else.
Because we show only a part of the wallpaper and "cut away" the area of
the panel in WorkspaceBackgrounds vfunc_allocate(), we also need to set
the rounded clips bounding rect to the rectangle we're actually showing,
otherwise the texture would be rounded in the region that's cut away.

This is the same as the vertical swipe gesture, but for keyboard

The animation handling is kinda split between layout (for the
keyboard slide), and keyboard (for the focus window slide). It
would be nice to have more fine grained control on those, so
move the animation handling altogether to keyboard.js as a start.
This is roughly similar, except that transformations apply to
the Keyboard actor, instead of the keyboardBox (its parent). We
now queue a relayout after the animation in order to update the
chrome tracking.
The only layering break now is that we emit
layoutManager::keyboard-visible-changed in keyboard.js, its
purpose will be dropped in future commits, so leave it there for
now.

Gestures leaving the overview from a short distance result in an
ugly effect with the panel opacity transitionhaving a fixed duration.
Make this transition have the same duration (although in a hackish
way) so we avoid the ugly effect.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1643>
The gesture internally manipulates the main adjustment so one swipe
up brings up the overview, and a second swipe up brings the app
grid. The gesture also works in the other direction to get out of
the overview.
Internally, this is delegated on the OverviewControls, so the
adjustment is not leaked out of there. This however meant open
coding the gesture interaction so it can be directed from
overview.js code.

This will be set whenever an event controller is manipulating the adjustment.

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.

We now have multiple touch swipe gestures with matching fingers and

Some actors don't have the scale applied to them directly but are

When opening a large number of windows, the computed space and scale for
a layout can become negative due to the per-row/per-column spacing. This
is smaller than the initial values of lastSpace and lastSpace, leading
to a null return which then causes all sorts of other issues resulting
in the workspace becoming invisible.
This change ensures that the function always returns a layout, even if
it may look a bit broken and does not conform to the scale/space
requirements which are impossible to fulfill for the given number of
windows. It's better than displaying nothing, since it allows users to
move/close windows and restore this to a more usable state.

The icon and close button might be overlapping the window actor but
were not considered in has_overlaps() which gets used to decide whether
to offscreen the actor for transparency. Since currently the icon is
visible when the preview is dragged and the whole actor is turned
transparent, the opacity will not be applied to everything as a whole
but the child actors individually. This leads to the window becoming
visible behind the icon.

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.

Checking whether the item is empty is now the history’s job, per the

The effect of this is that we call _history.addItem(), and thereby move

of whitespace); clearing the input field and pressing Enter becomes a
quick way to jump back to the end of the history. (The current history
item is not overwritten if the input is empty.)

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.

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.

Previously we used a bunch of heuristics for this. We checked if velocity
was directed towards the nearest snap point and its value was larger than
a threshold. If it is, we completed the swipe, otherwise we cancelled it.
This was good enough at the time, because this code was originally written
for back/forward swipe. Since then, the swipe tracker was extended to
handle arbitrary snap points and not just 0 and 1, or -1 and 0, depending
on text direction. After that it was iterated on, but never significantly
redone.
This worked well enough, but had two problems:
1. In some cases, notably overview, it may be wanted to be able to swipe
through multiple pages at once. This wasn't really possible because we
always picked the adjacent snap point.
2. Since we can't do that well, we want to restrict swipes to one page at a
time. It was done in a rather hacky way by clamping the position into
[-1, 1] range from the place where we started the swipe. This works
if we start the swipe from idle position, but if an animation was
already going, the range would be clamped to arbitrary values, and very
likely containing only one snap point, which we already swiped past at
this point. In this case, finishing the swipe would cancel it regardless
of velocity. This means that if one tries to quickly move through
carousel pages via swiping, half of the swipes will be inexplicably
cancelled.
We'll use the deceleration formula from
https://medium.com/@esskeetit/how-uiscrollview-works-e418adc47060#10ce
to calculate then projection point, then pick the nearest snap point and
calculate the duration as we did before. It works well enough for short
distances, but has two problems:
1. It caps the maximum distance at a pretty low value - about 5 pages in my
testing.
2. With how we pick the nearest snap point, it's too easy to accidentally
cancel the swipe,
To combat the first problem, we can modify the curve: only use linear
function at small distances, and smoothly transition it to a parabola
further.
For the second problem we can add two special cases: first, if the swipe
ended up between the initial snap point and the next one, we always prefer
the latter. Second, a good old velocity threshold for cancelling.
We'll also use a slightly smaller deceleration value for touchpad: 0.997
instead of 0.998.
Now that we can pick any snap point, the [-1, 1] clamping doesn't make
sense anymore, so instead let's replace it with a more flexible
mechanism: if we're near a snap point, pick its adjacent snap points.
Otherwise, take the two nearest snap points, and take their adjacent
snap points. This way we have 3 snap points to choose from when
starting a swipe from an idle position, and 4 if we start during an
ongoing transition.
This way, if we've just swiped from snap point n to n+1, the transition
will pick snap points n-1, n, n+1, n+2 and if we swipe again, we will
likely land on n+2. During that transition, if we swipe again, it will
likely have already passed the snap point n+1, so this time the available
snap points will be n, n+1, n+2, n+3, so we can swipe again and it will
still complete, and so on.
This will make it easy to allow multi-page swipes as well, by just
removing the clamping.

In some cases we may get anevent with very low delta at the end of the
swipe. While we can't completely ignore them, we can smooth them using a
scroll history, similarly to what GTK kinetic scrolling does: keep track
of the last 150ms of events, and sum their deltas when calculating the
velocity.
The logic is based on what GTK does in GtkGestureSwipe and
GtkEventControllerScroll.

Let empty input result in an error, just like other invalid commands

message “Text was empty (or contained only whitespace)” which it shows

Resource icons are added to the fallback icon theme, so they won't
get used if a matching icon is found in the configured theme.
That includes fallback names, so Adwaita's "window-close-symbolic"
takes precedence over "window-close-24-symbolic" in hicolor.
Fix this by using a custom name for a custom icon.

The Message class this is derived from unconditionally adds a close
button with 0 opacity that only gets shown on hover for messages that
can actually be closed. The MPRIS MediaMessage however can never be
closed and having a close button can cause the title to be cut short
unexpectedly.
Similarly the secondary text which other notifications use to display
the notification time is always left empty here as well.

So far, we couldn't allow workspace scrolling outside the overview
because scroll events were always sent to clients. However mutter
was changed recently to pass on scroll events when the mouse button
modifier (usually super) is pressed, which allows us to enable the
same workspace scrolling as in the overview now.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1612>
The design now calls for super-scroll for workspace switching
in the session, however it is currently only possible for
SwipeTracker to either handle scroll events or not.
In order to support the new use case, add a new :scroll-modifiers
property that allows specifying modifiers for which scroll events
are handled.

The code to update the actor position based on the cursor and current
scale was run in a 'new-frame' handler. This is working fine when
animations are enabled, but when they are turned off this does not work.
This is because the 'new-frame' signal is emitted before the changes for
that frame are applied. So with animations off the position was only
ever updated with the starting values. As a result the shrunk actor was
not being dragged by the position where it was clicked, but by where it
was clicked in the original size, which is likely not even on the shrunk
actor.
This change now also updates the position in the onComplete handler
which gets run with the final scale, even if the duration is 0.

Next commit will bind the workspace state adjustment to the snap
adjustment in WorkspacesView, and we'll need the preparation
steps but not the easing of the state adjustment.

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.

Nowadays gjs allows to omit get/set accessors for read-write properties,
and will define reasonable defaults in that case. In many cases we don't
need anything more than the default handling, let gjs handle those props.

The app grid itself now is horizontal, and is displayed beneath
workspaces, above the dash. This makes the indicator animations
out of place, as they're not coming from the edge anymore.

The new window preview overlay requires getting the app icon for a
window from the window tracker when it gets initialized. The window
tracker listens for the same 'window-added' signal on the MetaWorkspace
that the gnome-shell Workspace listens for to add the window preview.
The window tracker however reconnects all its signal handlers whenever
the number of workspaces changes, which means that its signal handlers
get called after the ones in Workspace ones. So by the time the
'window-added' handler in Workspace is called, the window tracker does
not have an app associated with the window.
To fix this ensure that all window related signal handlers in Workspace
are run after the ones in the window tracker.

Currently, there's one animation for the whole canvas. While it looks fine
with just one screen, it causes windows to move between screens when
switching workspaces. Instead, have a separate animation on each screen,
and sync their progress so that at any given time the progress "fraction"
is the same between all screens. Clip all animations to their screens so
that the windows don't leak to other screens.
If a window is placed between every screen, can end up in multiple
animations, in that case each part is still animated separately.

Currently, the workspace swipe transition only has one workspace in each
direction. This works until you try to do multiple swipes in quick
succession. The second swipe would continue the existing transition, which
only has 2 or 3 workspaces in it, and will hit a wall.
To prevent this, take all workspaces and arrange them into a column or row,
depending on the layout, and use that as a transition.
For the transition that happens when focusing a window on another workspace
(for example, via Alt+Tab), still use only two workspaces instead of all of
them.
Since we don't support layouts other than single rows/columns anymore,
diagonal transitions aren't supported anymore, and will be shown as
horizontal or vertical instead.
Since nw alt-tab and gesture transitions are different, don't allow to do
both at once, that is, disable swipe tracker when a programmatic transition
is going. This will also conveniently cancel a gesture transition if a
programmatic one is initiated while a gesture is in progress.

In future we will need to use window clones to better support multiple
monitors. To avoid having to hide every window, show wallpapers behind
the workspace transition: one per monitor.
Put the wallpaper into a separate class right away, later it will be
useful to make the animation per-monitor.

Simplify the code a bit. The workspace group is relatively self-contained,
so split it from the general animation. Reimplement _syncStacking().

We always request a natural width based on the maximum thumbnail scale,
but may very well use a smaller scale when allocating. This currently

Accessing GObject properties from JS has proven to be quite slow because
of the JS->C->JS roundtrip involved. With the WindowPreview this
actually has an impact since we're accessing those properties very often
while creating new layouts.
So cache the boundingBox and the windowCenter properties of the
WindowPreview using a this._cachedBoundingBox JS object. This might
speed up opening the overview with lots of open windows significantly.

Make computeScaleAndSpace() return an array including scale and space so
we no longer have to access the layout object from outside.
With this we also no longer need to set layout.space, since only the

Start cleaning up the whole mess around the layout object a bit and
return a new object in the LayoutStrategies computeLayout()
implementation. This object is supposed to be opaque to the API user and
will only be passed to the layout strategy.

clean that up later.

When the original animation was implemented, workspaces would only
ever be added at the end. We therefore got away with not having a
separate EXPANDING stage corresponding to the existing COLLAPSING
one when animating out.
Since support for creating in-between workspaces via DND was added,
this is no longer the case. And now that the thumbnails are centered,
the jump is quite noticeable.
Address this by adding new transitional states, so that we can
expand new thumbnails before scaling them in.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1609>
Make the slide property control the workspace scale, so that new workspaces
scale up, and destroyed workspaces scale down. The scale is done horizontally,
and only slightly vertically, as per design direction.
Rework the state tracking mechanism to remove the COLLAPSING state, since there's
no split between sliding out and collapsing anymore. Also remove the corresponding
'collapse-fraction' property from WorkspaceThumbnail.
Make ThumbnailsBox.vfunc_get_preferred_width() consider the slide-position property.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1593>
There are situations where MetaWorkspaceManager and ThumbnailsBox disagree
on the number of workspaces, for example when animating them out. It's more
important to follow the visible number of workspaces while they're updated.
Make vfunc_get_preferred_width() and vfunc_get_preferred_height() use the
current number of workspace thumbnails to calculate their sizes, instead of
MetaWorkspaceManager's n-thumbnails property.
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1593>
ThumbnailsBox currently allocates each workspace thumbnail using their
porthole size, and scales them down using scale-x and scale-y. This is
slightly problematic since it doesn't allow for properly styling these
thumbnails through CSS.
Rework ThumbnailsBox to allocate workspace thumbnails at their actual
sizes, and scale down the '_contents' actor inside WorkspaceThumbnail.

Allocate workspace thumbnails horizontally. This requires introducing code
to handle the RTL direction. Do a small rewrite of the DnD hover method to

This is now all centralized in the apps page, so move the workspaces
thumbnails to ViewSelector's apps page. This allows us to remove
all the slider controls too, since they're now unused.
The transition between showing the workspaces, and the app grid, is
based on the most recent mockups: scale and move it down, and fade it
out.

Now that there's only a ACTIVITIES and a SEARCH page, the old method of handling
keyboard tabbing (extra parameters to ViewSelector._addPage()) limits what we can
do.

Add them both in a StBoxLayout subclass with a vertical layout. This
new ActivitiesContainer class already contains an adjustment controlling
the transition between workspaces and app grid states, and althought it
is internal to it, it'll be easy to integrate with gestures in the
future.
Notice that AppDisplay is added before WorkspacesDisplay. That's because
we want the paint order to paint WorkspacesDisplay on top of AppDisplay.
Switch the ViewsPage enum to call this page ACTIVITIES, and adjust the
only caller in OverviewControls to it. At last, rename '_appsPage' to
'_activitiesPage' to also reflect the name change.
The usefulness of organizing this code in pages is lost here, but this
is a transitional state, and pages will be removed in future changes.

Only the area used by favorite apps can be used as drop targets, it
is not possible to add new favorites between the running apps at the

WokspacesDisplay simply remaps the scroll direction into the next
workspace, but that doesn't account for the new horizontal layout.

on the vertical axis.

The scroll adjustment's upper value corresponds to the number of

Now that apps either appear in the dash or the app grid, it makes

We use a custom actor to make sure that the show-apps button remains

With the transparent top bar in the overview, constraining to the

The code previously was using CSS to define row/column spacing and
padding which was combined with a subicon size computed in code relative
to the requested icon size.
In smaller icon sizes it was possible for the CSS spacing+padding + the
size of the two subicons to exceed the requested icon size. This then
would lead to the label being pushed down for app folders compared to
other icons.
Another more severe issue caused by this would happen if the first item
in an icon grid was an app folder. Then the calculation for the maximum
allowed icon size could be off, leading to all icons in the grid
becoming smaller than actually necessary.
This commit changes this to use homogeneous row and column layouts to
evenly distribute the remaining spacing instead of using a fixed CSS
value.
