Add support for per client randr-resolution change emulation using viewport,
for apps which want to change the resolution when going fullscreen.
Partly based on earlier work on this by Robert Mader <robert.mader@posteo.de>
Note SDL2 and SFML do not restore randr resolution when going from
fullscreen -> windowed, I believe this is caused by us still reporting the
desktop resolution when they query the resolution. This is not a problem
because when windowed the toplevel window size includes the window-decorations
so it never matches the emulated resolution.
One exception would be the window being resizable in Windowed mode and the
user resizing the window so that including decorations it matches the
emulated resolution *and* the window being at pos 0x0. But this is an
extreme corner case. Still I will submit patches upstream to SDL2
and SFML to always restore the desktop resolution under Xwayland,
disabling resolution emulation all together when going windowed.

On pointer enter notification, Xwayland checks for an existing pointer
warp with a `NULL` sprite.
In turn, `xwl_pointer_warp_emulator_maybe_lock()` checks for an existing
grab and the destination window using `XYToWindow()` which does not
check for the actual sprite not being `NULL`.
So, in some cases, when the pointer enters the surface and there is an
existing X11 grab which is not an ownerEvents grab, Xwayland would crash
trying to dereference the `NULL` sprite pointer:
#0 __GI_raise ()
#1 __GI_abort () at abort.c:79
#2 OsAbort () at utils.c:1351
#3 AbortServer () at log.c:879

This prevents multiple scroll events happening for wayland compositors
which send axis values other than 10. For example, libinput will
typically return 15 for each scroll wheel step, and if a wayland
compositor sends those to xwayland without normalising them, 2 scroll
wheel steps will end up as 3 xorg scroll events. By listening for the
discrete_axis event, this will now correctly send only 2 xorg scroll
events.
The wayland protocol gurantees that there will always be an axis event
following an axis_discrete event. However, it does not gurantee that
other events (including other axis_discrete+axis pairs) will not happen
in between them. So we must keep a list of outstanding axis_discrete
events.

In the typical pattern in games of "hide cursor, grab with a confineTo,
warp constantly the pointer to the middle of the window" the last warping
step is actually rather optional. Some games may choose to just set up a
grab with confineTo argument, and trust that they'll get correct relative
X/Y axis values despite the hidden cursor hitting the confinement window
edge.
To cater for these cases, lock the pointer whenever there is a pointer
confinement and the cursor is hidden. This ensures the pointer position
is in sync with the compositor's when it's next shown again, and more
importantly resorts to the relative pointer for event delivery.

However, all tools (and the pointer) share conceptually the same VCP
on Xwayland, so have cursor changes trigger a xwl_cursor update on
every tool (and the pointer, again). Maybe Xwayland could keep track
of the most recent device and only update that cursor to get better

Sometimes, Xwayland will try to use a cursor that has just been freed,
leading to a crash when trying to access that cursor data either in
miPointerUpdateSprite() or AnimCurTimerNotify().
CheckMotion() updates the pointer's cursor based on which xwindow
XYToWindow() returns, and Xwayland implements its own xwl_xy_to_window()
to fake a crossing to the root window when the pointer has left the
Wayland surface but is still within the xwindow.
But after an xwindow is unrealized, the last xwindow used to match the
xwindows is cleared so two consecutive calls to xwl_xy_to_window() may
not return the same xwindow.
To avoid this issue, update the last_xwindow based on enter and leave
notifications instead of xwl_xy_to_window(), and check if the xwindow
found by the regular miXYToWindow() is a child of the known last
xwindow, so that multiple consecutive calls to xwl_xy_to_window()
return the same xwindow, being either the one found by miXYToWindow()
or the root window.

wl_keyboard::leave needs to be handled in the same way as its

Moreover, it appears the device is neither enabled nor activated

Emulate pointer warps by locking the pointer and sending relative
motion events instead of absolute. X will keep track of the "fake"
pointer cursor position given the relative motion events, and the
client warping the cursor will warp the faked cursor position.
Various requirements need to be met for the pointer warp emulator to
enable:
The cursor must be invisible: since it would not be acceptable that a
fake cursor position would be different from the visual representation
of the cursor, emulation can only be done when there is no visual
representation done by the Wayland compositor. Thus, for the emulator
to enable, the cursor must be hidden, and would the cursor be displayed
while the emulator is active, the emulator would be destroyed.
The window that is warped within must be likely to have pointer focus.
For example, warping outside of the window region will be ignored.
The pointer warp emulator will disable itself once the fake cursor
position leaves the window region, or the cursor is made visible.
This makes various games depending on pointer warping (such as 3D

Translate grabbing a pointer device with confineTo set to a window into
confining the Wayland pointer using the pointer constraints protocol.
This makes clients that depend on the pointer not going outside of the
window region, such as certain games and virtual machines viewers, to
function more properly.

If there was an relative pointer motion within the same frame as an
absolute pointer motion, provide both the absolute coordinate and the
unaccelerated delta when setting the valuator mask.
If a frame contained only a relative motion, queue an absolute motion
with an unchanged position, but still pass the unaccelerated motion
event.
If the wl_seat advertised by the compositor is not new enough, assume
each relative and absolute pointer motion arrives within their own
separate frames.

Wait until wl_pointer.frame with dispatching the pointer motion event,
if wl_pointer.frame is supported by the compositor. This will later be
used to combine unaccelerated motion deltas with the absolute motion
delta.

Generating relative and absolute movement events from the same input
device is problematic, because an absolute pointer device doesn't
expect to see any relative motion events. To be able to generate
relative pointer motion events including unaccelerated deltas, create a
secondary pointer device 'xwayland-relative-pointer', and use that for
emitting relative motion events.

Put device class initialization in init_[device_class](xwl_seat) and
releasing in release_[device class](xwl_seat). The purpose is to make
it easier to add more type of initialization here later, without making
the function too large.

The way we map the touch absolute device to screen coordinates can't
work across wl_output mode and geometry events. Instead, set up
a fixed coordinate space, and transform touch events according to
the screen coordinate space as they happen.

The checks in xwayland's XYToWindow handler pretty much assumes that the
sprite is managed by the wl_pointer, which is not entirely right, given
1) The Virtual Core Pointer may be controlled from other interfaces, and
2) there may be other SpriteRecs than the VCP's.
This makes XYToWindow calls return a sprite trace with just the root
window if any of those two assumptions are broken, eg. on touch events.
So turn the check upside down, first assume that the default XYToWindow
proc behavior is right, and later cut down the spriteTrace if the
current device happens to be the pointer and is out of focus. We work
our way to the device's lastSlave here so as not to break assumption #1
above.

Since xwayland's initial commit we have had a check to not process
wayland modifier events while one of our surfaces has keyboard focus
since the normal xkb event processing keeps our internal modifier
state up to date and if we use the modifiers we get from the
compositor we mess up that state.
This was slightly changed in commit
10e9116b3f to allow the xkb group to be
set from the wayland event while we have focus in case the compositor
triggers a group switch.
There's a better solution to the original problem though. Processing
queued events before overriding the xkb state with the compositor's
allows those events to be sent properly modified to X clients while
any further events will be modified with the wayland modifiers as
intended.
This allows us to fully take in the wayland modifiers, including
depressed ones, which fixes an issue where we wouldn't be aware of
already pressed modifiers on enter.

Emitting a LeaveNotify event every time the pointer leaves an X11 window
may confuse focus follow mouse mode in window managers such as
mutter/gnome-shell.
Keep the previously found X window and compare against the new one, and
if they match then it means the pointer has left an Xwayland window for
a native Wayland surface, only in this case fake the crossing to the
root window.

This partially reverts commit c1565f3.
When the pointer moves from an X11 window to a Wayland native window,
no LeaveNotify event is emitted which can lead to various unexpected
behaviors like tooltips remaining visible after the pointer has left the
window.
Yet the pointer_handle_leave() is called and so is the DIX CheckMotion()
but since the pointer enters a Wayland native window with no other
Xwayland window matching, DoEnterLeaveEvents() does not get invoked and
therefore no LeaveNotify event is sent to the X11 client at the time the
pointer leaves the window for a Wayland native surface.
Restore the XYToWindow() handler in xwayland-input that was previously
removed with commit c1565f3 and use that handler to pretend that the
pointer entered the root window in this case so that the LeaveNotify
event is emitted.
