The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.
In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.
Otherwise we'll show a dangling cursor but otherwise the cursor will be
updated by other code paths, so we end up with a weird cursor in the
middle of the screen that doesn't move.
It is possible for updateOutputs to be called when a pageflip is pending.
Freeing a DrmOutput with a pending pageflip is not allowed (see ~DrmOutput assert - the page flip handler will be called on the freed memory, possibly leading to use-after-free).
This works around the problem by delaying the destruction with teardown().

In atomic setting mode, when external display tears down, it will blank
crtc with dump buffer by legacy api, then re-plug the external display,
the blank can not be removed. We think the blank is not needed in atomic
mode setting.

Currently in order to load an Xcursor theme, kwin uses libwayland api,
which looks really awkward because of the way how the compositor talks
to itself via the internal connection.
The main motivation behind this change is to limit the usage of kwayland
client api in kwin.
Since ScreenEdge no longer uses physicalDpiX() and physicalDpiY() from
the QPaintDevice class in favor of our own helpers, we need to ensure
that the X11 platform provides valid output physical dimensions.

We currently deal with three distinct coordinate spaces - the window
pixmap coordinate space, the window coordinate space, and the buffer
pixel coordinate space.
This change introduces a couple of helper methods to make it easier
to map points from the window pixmap space to the other two spaces.
The main motivation behind the new helpers is to break the direct
relationship between the surface-local coordinates and buffer pixel
coordinates for wayland surfaces.
We don't need to bind disabled outputs to surfaces that overlaps them.
This prevents error down the line and warnings about ignoring surface.enter events with Qt.

In previous code we used to update/show cursor even when the pointer
device was present, e.g mobile device. Guard it behind the cursor
enabled check.
