I did some research with the result that such comparisons are indeed
not standardized to be legal before C++14. In C++14 they are.
These microoptimizations can thus be re-enabled when C++14 becomes
the required version.
Summary:
This is basically a copy of the screen edges config module with
everything removed which does not matter. This is lazy and could
be done with more code sharing. But it would be better to redesign
both kcms in a modern way instead of investing lots of time on
sharing code.
Test Plan:
Installed, opened it and verified it had the config selected
I had manually set.

Summary:
The new touch gestures activated for the same actions as configured for
mouse pointer actions. This has disadvantages as the only configured
default screen edge action cannot be triggered (corner) on touch. On the
other hand setting a default touch gesture would be rather annoying with
pointer as a default.
So overall it makes sense to split the actions and have dedicated pointer
and dedicated touch actions.
This change introduces the first part of it and splits the handling in
general. We now have:
Activates for pointer and touch:
* client (auto-hiding panels)
Activates for pointer only:
* the configured action
* virtual desktop switching
* callbacks
Activates for touch only:
* the new touch action
The touch actions are implemented similar to the pointer actions which
slight improvements in the code which will be backported to the pointer
actions.
Introducing callbacks will be the next step. I plan to do it a little bit
different by using QActions as that's what KWin internally uses for
everything except screen edges.
Test Plan: Manual testing and improved auto tests

Summary:
So far KWin did not properly handle popup windows. That is when a popup
surface got created and a click outside the surface happened KWin did not
send out the popupDone Wayland event.
This change makes KWin aware of whether a surface is a popup and tracks
through a new PopupInputFilter whether there are popup windows. In case
there are popups the new filter waits for mouse press events and cancels
the popups if the press does not happen on any surface belonging to the
same client. To quote the relevant section of the Wayland documentation:
The popup grab continues until the window is destroyed or a mouse
button is pressed in any other client's window. A click in any of the
client's surfaces is reported as normal, however, clicks in other
clients' surfaces will be discarded and trigger the callback.
So far the support is still incomplete. Not yet implemented are:
* support xdg_shell popup windows
* verifying whether the popup is allowed to be a popup
* cancel the popup on more global interactions like screen lock or
kwin effect

As pointed out by the Valgrind trace in #363224, delaying the signal causes
the EffectWindow* argument to become invalid before the connected slot is
called (this is because Qt discards only delayed signal->slot calls where
the receiver gets deleted meanwhile, not the sender and definitely not
a random argument.
If the supposed glitches really happen, they should get fixed correctly,
and for all cases (I doubt only desktop number would be involved but
not e.g. shaded or minimized states).

Summary:
Each Edge creates a SwipeGesture for touch activation. The swipe needs to
be a single finger starting from the edge into the screen for at least
20 %. The SwipeGesture and GestureRecognizer is extended to support the
use cases of the touch screen edge swipe.
New features supported by the gesture system are:
* minimum and maximum position
* a minimum delta for the swipe
* progress signal based on the minimum delta
* starting a swipe with a start point
The Edge has the progress signal connected to its approach signal, thus
visual feedback is provided through the screen edge effect.
The screen edge system supports touch only for the edges (corners are
too difficult to activate on touch screens). At the moment the following
features are supported:
* screen edge show/raise of windows (e.g. auto hidden panels)
* trigger the configured action
* trigger the configured callback function (e.g. script)
In future it might make sense to add a touch specific configuration
action to support different actions for screen edges activated by mouse
and touch.

Summary:
This change adds global touchpad swipe gestures to the
GlobalShortcutsManager and hooks up the swipe gestures as defined at the
Plasma Affenfels sprint:
* swipe up: Desktop Grid
* swipe down: Present Windows
* swipe left: previous virtual desktop
* swipe right: next virtual desktop
The main work is handled by two new classes: SwipeGesture and
GestureRecognizer. This is implemented in a way that it can be extended
to also recognize touch screen gestures and pinch gestures.
The SwipeGesture defines what is required for the gesture to trigger.
Currently this includes the minimum and maximum number of fingers
participating in the gesture and the direction. The gesture gets
registered in the GestureRecognizer.
The events for the gesture are fed into the GestureRecognizer. It
evaluates which gestures could trigger and tracks them for every update
of the gesture. In the process of the gesture tracking the
GestureRecognizer emits signals on the Gesture:
* started: when the Gesture gets considered for a sequence
* cancelled: the Gesture no longer matches the sequence
* triggered: the sequence ended and the Gesture still matches
The remaining changes are related to hook up the existing shortcut
framework with the new touchpad gestures. The GlobalShortcutManager
gained support for it, InputRedirection and EffectsHandler offer methods
to register a QAction. VirtualDesktopManager, PresentWindows and
DesktopGrid are adjusted to support the gesture.

Summary:
Consider the following situation: we have three InputEventFilter linked
in the sequence A - B - C.
The input filters are processing pointer motion events. The expected
behavior is that the new motion is processed in the sequence
A -> B -> C
So far this did not work correctly if the pointer gets warped during the
processing. If e.g. filter B warps the pointer we get a motion sequence:
A (1) -> B (1) -> A (2) -> B (2) -> C (2) -> C (1)
The filters following the one warping the pointer get first the newer
than the older position. This is obviously wrong. Unfortunately it is not
just a theoretical condition, but a condition happening when interacting
with the screenedges, which warp the pointer.
This change introduces a PositionUpdateBlocker in
PointerInputRedirection::processMotion to ensure that a processMotion
call finishes prior to the next update. If the PositionUpdateBlocker is
blocked the new position gets scheduled and processed once the
PositionUpdateBlocker gets destroyed.
With this we get the expected sequence for B warping pointer:
A (1) -> B (1) -> C (1) -> A (2) -> B (2) -> C (2)
This should hopefully improve the interaction with screen edges on
Wayland.
CCBUG: 374867
Test Plan:
Added an auto test demonstrating the issue of incorrect
ordering caused by screenedges. Prior to the change the test is failing.
