Summary:
Workaround QtBug-68997
Deleting of a RenderControl/render controlled window triggers deletion
of other queued deleted items, putting KWin in a corrupt state. See Qt
bug report.
Deleting this queued means we know we don't have anything else going on
in the stack which should make this somewhat safe.
BUG: 395346
Test Plan:

Set an Aurorae theme. Closed some windows. Things still worked as before

Summary:
Currently, effects like Maximize, Slide Back have problems with setting
WindowForceBlurRole. They store previous state of WindowForceBlurRole.
This is wrong. Instead they should either ignore previous state of
WindowForceBlur or refcount forced role.
There's no need for refcounting right now. For example, if several effects
force blur or background contrast, they are most likely in a conflict.
Please notice that the Desktop Grid effect uses the Present Windows
effect only to calculate transformations.
Some other problems with the code that sets WindowForceBlurRole:
* Maximize effect stores previous state of WindowForceBlurRole only
for one window. It ignores the fact that there could be several
active maximize animations;
* Desktop Grid/Present Windows/Slide back don't clean after themselves.
So, after using those effects for good amount of times, memory usage
will bump.
Test Plan:
* Enabled blur for Konsole
* Maximized Konsole
* Activated Present Windows
* Activated Desktop Grid
* Raised another window(to trigger Slide Back)

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:
Instead of seeing the cursor <--> on the left edge you now see an icon
that looks like |<- .
This brings kwin decorations in line with GTK CSD icons.
In theory this is also useful to tell which window will resize in the
case of side-by-side windows (regardless of whether borders are on or
not). In practice with the adwaita icon theme I tested with it's not
very intuitive to realise which is which till you learn the icon.
Change is more involved than it should be as Qt::CursorShape doesn't
have these entries, and I don't want to shadow that enum internally or
have
to change kwin effect code.
Specifics depend on cursor icon theme if they are not present it will
fallback to the <--> icon. (Breeze does not have them currently)
Test Plan:
Resized some windows (on X and on Wayland)
Correct icon appeared on Adwaita
Existing icon appeared on Breeze

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

Differential Revision: https://phabricator.kde.org/D10811
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.
