Summary:
There are several spaces that have to be considered in `GLRenderTarget::blitFromFramebuffer`:
* KWin logical space: the origin is located at the global top-left corner
* display space: the origin is located at the top-left corner of monitor/display
* OpenGL screen space: the origin is located at the bottom-left corner of monitor/display
Given `s`, which is in the KWin logical space, we have to transform it to the display space, then to the OpenGL screen space:
* KWin logical space -> display space: `y' = s.y() - s_virtualScreenGeometry.y()`
* display space -> OpenGL screen space: `y'' = s_virtualScreenGeometry.height() - y'`
Overall, `srcY0` and `srcY1` should be written as follows:
```
srcY0 = s_virtualScreenGeometry.height() - (s.y() - s_virtualScreenGeometry.y() + s.height())
srcY1 = s_virtualScreenGeometry.height() - (s.y() - s_virtualScreenGeometry.y())
```

Summary:
KWin is not designed to run as root. It is not hardened enough and
there is a great risk that applications could attack KWin through
X11 properties, Wayland protocol requests, etc. to trigger stack or
heap overflows and execute random code. As clients connected to KWin
could be remote there is a great risk in running KWin as root. Also
clients on the same system but started as a different user could
try to gain more privs by exploiting KWin.
Furthermore KWin is designed to not run as root. It interacts with
logind to get the devices opened which would require root. Whether
KWin would work as root at all is questionable.
We cannot guarantee that running KWin as root is secure, thus this
change disallows running KWin and thus a Wayland session as root.

Summary:
Our rule handling has had a grave error for years. Whenever a window
with a rule was openend or closed the kwinrulesrc was written back to
disk.
The reason for this behavior is that temporary rules need to be discarded
once they were used. For that there is a method discardUsed which invokes
requestDiskStorage whenever a rule for the window was found. But it did
not check whether there was a rule requiring this.
This change modifies the discardUsed to track whether it changed a rule
and only writes back in case there was a change.

Summary:
The drm platform has a special handling for touch events while the
screen is in dpms. All touch events are filtered out, but a double
tap wakes up the screen.
Due to the filtering out of the events the idle timers were not reset.
So if you only double tapped, the screen turned on, but not off again.
This change updates the timestamp after double tap, so that the idle
timers are restarted. All other events are still filtered out, to not
have "fake" events (e.g. smart phone in pocket) wake up the device.

Summary:
From Wayland documentation:
"When a seat's focus enters a surface, the pointer image is undefined and
a client should respond to this event by setting an appropriate pointer
image with the set_cursor request."
KWin's interpretation so far for the undefined pointer image was to
remove the pointer image when entering a surface waiting for the client
to set a cursor image. This can result in a short flicker as there might
be a frame without a cursor image.
This patch changes the behavior by keeping the previous image till the
application set a new one. This brings some advantages:
* if the application is not responding a cursor is still shown
* if the same cursor is used as in the previous window we don't have a
flicker
CCBUG: 393639
Test Plan: I cannot see the flicker, so only tested with the adjusted tests

Summary:
`QGuiApplication::primaryScreen()->logicalDotsPerInch()` sometimes reports incorrect scale value, for example 95.951 (or even lower) instead of 96.0 at 1x scale and this caused to simply darken blurred areas instead of noising them.
This patch sets a minimum 1x scale for the noise texture, because realistically we will never be below that.

It was likely wrongly pushed before the KWayland changes, so it won't

Summary:
When you have two windows ontop of each other and you turn them
transparent, evidently you'll be able to see through them.
Not only does it look unpolished if the desktop window flashes through
your windows, it can pose a privacy risk as you'd be able to briefly
look through the lock screen.
This patch fades apps to black intead of to transparent. As this looks
weird for panels, so windows are also faded to opaque (if relevant) at
the same rate.
