Aurorae uses a QQuickWindow that receives an implicit scale through the
QPA. Unfortunately there's a known quirk with device pixel ratio not
being followed when offscreen surfaces are never shown and an
independent render control is used.
Without this QQuickRenderControl::grab ends up using a buffer the size
of the window * dpr, but with the contents rendered at 1x in the corner
along with incorrect device pixel ratio information.
This patch copies a used solution from EffectQuickView. This can be
resolved more neatly with newer Qt.

Since normal geometry is now rounded, we need to make sure to round
anything that should match that geometry, otherwise we risk things
peeking out of the normal geometry.

Before this commit, the device pixel ratio of the cursor was set to ignore
the Xwayland scale override, while the size of the cursor surface was scaled.
This change removes the scaling of the cursor surface size, to make the cursor
be no longer cut off in rendering.

Converting to wl_fixed is lossy. Especially for non-round values like 1.15.
This causes various visual glitches and off sizes.
Given we're using units of 120ths for the fractional scale protocol it makes sense
to fix the passed values for anything else over the wayland protocol.

Testing done:
ran a 1920 screen at 1.15 scale, got a logical size of 1670 which matches what it should be
The only one that does it differently is the DRM backend and it's just
an extension that takes GBM into account, otherwise it's effectively
copy-pasted code.
We need to register data types such as QVector<KWin::VirtualDesktop *>
both for QML and JavaScript scripts.
If you have no JavaScript scripts enabled, those container types won't
be registered and QML will fail to read properties such as
Window.desktops, which can result in already visible windows animating
opacity from 0 to 1 when opening overview effect.
To fix that, register all accessible data types in scripting apis in
Scripting::init().
We want floating tiles to be activatable, but also dismiss the effect by
clicking on the whitespace.
The current solution doesn't work as a floating tile that is in turn
split will pull focus from the children meaning those tiles can't be deleted.
Rather than special casing and z-manipulation we can simplify everything
by moving tile dismissal to the root of the effect and appropariately
propagating the event.

there is no practical reason I can see for why this should be limited to
stderr only. we are not reading or otherwise consuming stdout, we should
just pass it on.
Context: If a display is removed, the corresponding TileManager is removed with it. This in turn removes every one of its Tiles with it, and when a Tile's destructor is called, it attempts to find a new replacement tile for any windows it was previously managing.
However, if the Tile is removed because its corresponding TileManager has been removed, this has the potential to cause a segfault in KWin, causing it to crash (I suspect a possible race condition? but not sure).
This MR correctly evacuates custom tiled windows & migrates quick tiled windows upon output removal.
BUG: 465522
Use input device specific apis to change the position of the cursor. The
main reason to do so is to break the assumption that Cursor position is
the same as pointer position, which I would like to rely on later to
merge tablet and pointer cursors.
