Summary:
This problem appears if shadow corner tiles are too big and
some window has size smaller than 2 * shadowTileSize.
This change tries to address the problem above by exclusing
overlapping tile parts. If there are any two overlapping corners
then tile between them(top/right/bottom/left) is not rendered.
Also, because some corner tile parts can be excluded, corner tiles
are expected to be symmetrical(i.e. if we remove right half from
the top-left tile and left half from the top-right tile and
stick them together, they still look fine, there are no misalignments, etc).
Most shadows(e.g. shadows from Breeze) have such behaviour.
No tiles are overlapping

Overlapping tiles
{F5728516, layout=center, size=full}
And this is how it supposed to be
{F5728517, layout=center, size=full}
Test Plan:
* apply D11069 to Breeze
* in System Settings/Application Style/Window Decorations, choose "Very Large" shadow size
* open Konsole
* resize it to a minimum possible size

The main problem was that inside the effect there was manualVerticalAngle,
which did not represent the actual rotation angle of the cube during the
animation, but used to calculate the position of the reflection. The actual
angle was calculated on-the-fly and was not exposed outside.
Brief description of what the code does:
- variables currentAngle and verticalCurrentAngle now always represent the
current position of the cube. They are updated when one uses the mouse and
inside the rotateCube() method, which is called in prePaintScreen().
- two queues, animations (used for Start / Stop / Left / Right) and
verticalAnimations (used for Up / Down) are used for scheduling the animations
if i.e. user presses several keys in a row. The code checks whether the last
animation has finished (and thus we need to start a new one) inside
prePaintScreen() and postPaintScreen()
- when the animation starts, code saves the starting position of the cube
inside startAngle, startFrontDesktop and verticalStartAngle variables, which
are used to calculate the actual cube position during the animation later.
This is done by startAnimation() and startVerticalAnimation(), which also
calculates the QTimeLine curves needed for animation

Summary:
If the env var is 0 we calculate the cursor size based on the
physical resolution.
The size is multiplied by the output scale.
Either would make sense, together does not and reuslts in kwin
having massive cursors.
This patch is for 5.13.
For master I intend to kill this concept of "resolution dependent size"
on the KCM. We then should do wayland scaling on cursors properly no matter
what size the user selects which will work better for when we have
multiple screens.
I have a WIP patch pending for the latter, but it's too big for here.
It still involves deleting this code.

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
