Summary:
This patch caputres from the framebuffer using the framebuffer's
geometry, factoring in scale. We then keep the current normal DPI
framebuffer causing it to downsample there.
This is good because:
- it keeps the code very simple
- it's a performance optimisation. Blurring on 4k is naturally more
expensive than at regular DPI. Downsampling keeps it the same - and you
can't see a difference given it's high DPI and you're going to blur it
anwyay.
- it keeps kernel sizes somewhat resolution independent so it will look
just as blurry across multiple screens.
::doCachedBlur still needs doing.
Test Plan:
Ran an app
Ran the kwindowsystem blur test
Observed the right part of the window being blurred

Summary:
This method already translates to s_virtualScreenGeometry as the source
co-ordinates are in compostior space we should take scaling into account here too.
This method already supports resizing if source and target sizes do not match.
Calling funcitons can either double the size of the target if they want native resolution
or leave as-is if they want the result in standard DPI.
This implements scaling in the screenshot, magnifier and simple blur effect.
Test Plan:
Tested screenshot effect using spectacle.
I hit an (unrelated, was reproducible on master) crash whilst using this, so it is not fully tested
Ran magnifier effect manually

Summary:
There are a few places where KWin needs to read values from kcminputrc.
As I need to add yet another one it makes more sense to properly
structure it like in other cases and have only one kcminputrc hold in
the application. This also allows to better mock the config values in
the integration tests.

Summary:
Consider the case that capslock gets pressed and released.
In the case of Weston we have a sequence of:
1. Key press event
2. Modifier changed event
3. Key release event
4. Modifier changed event
KWin however used to send the events in the following sequence:
1. Modifier changed event (on key press)
2. Key press event
3. Modifier changed event (on key release)
4. Key release event
It looks like Xwayland is not able to properly process the sequence
sent by KWin. And in fact KWin's sequence is wrong as it sends a state
which does not match. We report that the caps lock is pressed in the
modifiers prior to the application getting informed about the key press
of caps lock.
This change aligns KWin's implementation to the behavior of Weston. The
main difference is that when modifiers change Xkb internally caches the
serialized modifier states. And KeyboardInputRedirection just forwards
the modifiers to KWayland::Server::SeatInterface once the processing has
finished. SeatInterface ignores the forwarding if no states changes, so
it is fine to do it that way.
BUG: 377155
Test Plan:
Not yet tested with an affected Xwayland as I only have 1.18 and the
problem started with 1.19. But verified the sequence of events with WAYLAND_DEBUG
and caps lock stil working in QtWayland clients and Xwayland 1.18

Summary:
Another regression from enabling touch support on X11.
The approach window for pointer input gets unmapped as soon as the mouse
enters the window. This ensures that mouse motion events are not stolen
from other applications. But with the touch events we did not even react
on the enter event if it's not activated for pointer. The result was an
area around the screenedge being blocked for pointer input.
This change only creates and maps the approach window if the edge is
activated for pointer input.

Summary:
With the TabBox I observed the following issue:
1: trigger TabBox through screen edge
2: exit TabBox
3: trigger TabBox again through screen edge
Actual behavior: in step 3 the GUI does not show. If now using Alt+Tab
to show the TabBox the gui shows, but through screen edge it stays
broken.
Investigation showed that the difference is a direct show in screen edge
case and a delayed show in Alt+Tab case. Futher investigation shows that
an invalid geometry gets requested in the broken case. While this might
indicate an issue in another area it makes sense to protect KWin
internally against it and not to break rendering.
Thus this change ensures that a valid FBO does not get replaced by an
invalid sized FBO.
Test Plan:
Tested that Alt+Tab works correctly when triggered through
edge

Summary:
This is quite similar to the policy "window" - the main difference is
that windows from the same application share the layout. So only
switching to a window from another application changes the layout.

Summary:
This change introduces the initial support for keyboard layout switching
policies like in the X11 session. This first change only adds support for
Global and Virtual Desktop policy. This means the current layout is
stored in context to the current virtual desktop. Whenever one changes
the virtual desktop the previous layout is restored. If the user has not
yet navigated to this virtual desktop a switch to default layout is
performed.
This is the first code interacting with the new Virtual Desktop API which
is not based on integer ids. To fully support this the API is slightly
extended.
Test Plan: Added test case

Summary:
On Wayland it can happen that a window is still in the stacking order
although it is not visible. This is mostly the case for Plasma windows.
So far the slideback effect did not ignore those windows and as they are
higher in the stacking order than most other windows it blocked the
effect from working once a Plasma panel element got closed.
This change considers a window which has painting disabled in the
stacking order as not usable and thus filters out all those windows.

Differential Revision: https://phabricator.kde.org/D5462
Summary:
During pointer motion we already had the condition that an update of
focused pointer surface can only happen when no button is pressed. But
there are more conditions where we try to update the focused pointer even
if a button is pressed. E.g. if the stacking order changes.
This happens when trying to move one of Qt's dock widgets:
1. Press inside a dock widget
2. Qt opens another window, which is underneath the cursor
3. KWin sends pointer leave to parent window
4. dock widget movement breaks
This change ensures that also this sequence works as expected and the
pointer gets only updated when there are no buttons pressed, no matter
from where we go into the update code path.
BUG: 372876
Test Plan: Dock widgets in Dolphin can be moved now.

Summary:
By changing all kcfg to have arg="true" we can pass in the same
KSharedConfigPtr into all effects. This allows to have fake config in
the tests and in the planned effect demo mode.
Also it means that we don't have to hardcode the name kwinrc into the
files. In the configs - where we cannot access the effectshandler - we
use the define KWIN_CONFIG which gets generated based on the compile
time arguments.

Summary:
The KCM has a context property of the currently set theme index. This is
set before the decorations model is populated, so it is currently always
-1.
This model is populated after the constructor but before
KCModule::load().
KCModule::load is called from KCModule::showEvent so before
QQuickGridView will start doing anything with delegates.
This fixes the problem simply and also avoid parsing the config file
multiple times.
This bug was introduced in 5.9.4:
Someone made a (tested) change to make sure the view scrolled to the
right place on startup.
I then made a (tested) commit fixing the crash on exit
The author then updated his patch to my changes, but now in a way that
didn't work.

Summary:
There is a special mode in TabBox which is the noModifierGrab mode. This
is Alt+Tab active without a modifier being hold. This mode is entered
when being activated through screen edges (either pointer or touch). So
far this was not exposed to QtQuick and thus one could not end the mode
using pointer or touch. It is possible to select another window, but not
to activate it. That required the press of a keyboard key.
This setup is rather unfortunate. By exposing the mode to QtQuick we can
react from QtQuick side to it and invoke already exposed functionality to
select and item and directly activate it - existing left-over from the
Plasma Active window switcher.
Test Plan:
Tested on X11 and Wayland with an adjusted lnf package. It kind
of works, but there are additional issues on both X11 and Wayland.
