Use isNull on QSizeF to check for a zero delta instead of comparing it
with a default-constructed QSizeF, which in practice initializes to
(-1.0,-1.0). This caused relative motion events to be omitted if the
delta happened to be equal to (-1.0,-1.0), causing mouse jumping in some
applications.

In libinput 1.19, three new pointer axis events were added in order to
provide support for high-resolution scrolling.
LIBINPUT_EVENT_POINTER_AXIS is de-facto deprecated and new users of
libinput should use instead SCROLL_WHEEL, SCROLL_FINGER, and
SCROLL_CONTINUOUS.
Discrete deltas were replaced with v120 delta values. 120 corresponds to
a single discrete delta. Smaller values correspond to "partial" wheel
ticks.

The .clang-format file is based on the one in ECM except the following
style options:
- AlwaysBreakBeforeMultilineStrings
- BinPackArguments
- BinPackParameters
- ColumnLimit
- BreakBeforeBraces
- KeepEmptyLinesAtTheStartOfBlocks
Occasionally, I see complaints about the file organization of kwin,
which is fair enough.
This change makes the source code more relocatable by removing relative
paths from includes.
CMAKE_CURRENT_SOURCE_DIR was added to the interface include directories
of kwin library. This means that as long as you link against kwin target,
the real location of the source code of the library doesn't matter.
With autotests, things are not as convenient as with kwin target. Some
tests use cpp files from kwin core. If we move all source code in a src/
directory, they will need to be adjusted, but mostly only in build
scripts.
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.
Summary:
So far KWin didn't send axis_source, axis_discrete, and axis_stop. Even
though most of those events are optional, clients need them to work as
expected. For example, one needs axis_source and axis_stop to implement
kinetic scrolling; Xwayland needs axis_discrete to prevent multiple
scroll events when the compositor sends axis deltas greater than 10, etc.

FIXED-IN: 5.17.0
Test Plan:
* Content of a webpage in Firefox is moved by one line per each mouse
wheel "click";
* Scrolled gedit using 2 fingers on GNOME Shell, sway, and KDE Plasma;
in all three cases wayland debug looked the same (except diagonal scroll
motions).

Summary:
If KWin interacts with Libinput the RelativePointerManager interface
gets created on the Wayland server. The ForwardInputEventFilter does
forward the relative motion events in addition to the normal motion
events.
In order to properly support the relative motion events as they are
expected by the Wayland protocol the handling of pointer motion events
got slightly adjusted:
* Libinput Pointer event extended by the additional data points
* Libinput Pointer event carries the delta as a QSizeF instead of
QPointF
* PointerInputRedirection adjusted to take a pointer motion event with
more arguments
* Custom QMouseEvent subclass adjusted to carry the additional members
The DebugConsole is adjusted to show the relative motion events in
addition to the global position.
Test Plan:
Verified the manager object is created and verified the
events in DebugConsole. Unfortunately not aware of any test application.
