This ensures that fullscreen apps can always use the native mode.
Also ensure the root window is large enough for the output at its
current position with the native mode.

In the rootless case, Xwayland receives pointer motion events only while
the pointer is over one of its Wayland surfaces, so there's no need for
constraining them to RandR boundaries.
This also avoids them getting spuriously constrained when using RandR
emulation for modes larger than the default one.

Xwayland was sending incorrect pointer coordinates to X clients on
pointer enter events.
This was caused by calling CheckMotion() with a NULL event, which
prevented the pointer sprite hot coordinates from being updated
properly.
Fix this by constructing a proper DeviceEvent of type ET_Enter in
pointer_handle_enter, initializing it with the current timestamp
and EVENT_SOURCE_FOCUS, and passing it to CheckMotion() instead
of NULL.
This ensures the pointer sprite coordinates are correctly updated
when the pointer enters a window.

For cpu_family(), meson returns "sparc" for 32-bit sparc,
and "sparc64" for 64-bit sparc, regardless of the OS in use.
For cpu(), meson returns values like "sun4v" on Solaris/SPARC,
and doesn't promise stability of the values, or portability across
OS'es, unlike cpu_family().

Commit d36f66f15d ("Check for duplicate output names") would walk the
list of existing outputs and leases to check that no other existing

The change however, inadvertently reused the regular screen outputs when

Fix this by using the lease name, not the regular output names that we
already checked just above.

The commit referenced below partially resolved an issue with grabs being made
on the root window. Unfortunately it assumes that the application uses
the same client for all windows. VMware Workstation uses nested windows
for each VM, each of which runs its own process with this own client.
Theses windows are managed by the GUI which is the top level for the
application and maps the windows based on which tab is selected.
Because the VM windows issue a grab on the root window and don't share
the same client as the GUI, grabs don't work properly with global shortcut
inhibition being completely broken.
Getting the parent top-level of the nested windows fixes this issue.

(cherry picked from commit ec14ecf751)
Previously, when parsing multiple configuration files containing the same
section names, only the last occurrence of each section would be retained.
Earlier definitions were silently discarded due to unconditional memory
allocation and overwriting of pointers during parsing.
This resulted in incomplete or incorrect configuration state when users
intended to merge or extend configuration through multiple files.
The section parsing functions in Files.c, Flags.c, and Module.c now
accept existing section pointers. These functions allocate new memory only
if the input pointer is NULL, preserving earlier data when re-parsing.
read.c has been updated to detect and pass existing section pointers when
encountering duplicate sections across files, preventing loss of prior content.
With these changes, the parser properly accumulates and merges configuration
data across multiple files, ensuring that all relevant settings are preserved.

(cherry picked from commit 9b6f72395a)
Xwayland dispatches tablet tool tip events immediately when they arrive.
With compositors such as mutter and sway, it is not an issue because
their libinput backends synthetize axis events before tip events. In
other words, axis data and the tip status belong to different frames.
On the other hand, kwin sends axis and tip events in a single frame
(its libinput backend generates a single tip event with axis data
attached to it). Since the tip events are dispatched immediately,
they can have wrong information associated with them, for example tool
position or pressure. It results in undesired "streaks" when the user
presses the tablet tool against the tablet.

(cherry picked from commit 0235121c6a)
Xwayland has its own XYToWindow() handler to account for the case when
the pointer leaves an X11 surface to enter another Wayland native
window.
When that occurs, Xwayland will treat it as if the pointer had entered
the root window so that the X11 clients receive an appropriate leave
event.
When the pointer leaves the X11 surface, Xwayland will call
CheckMotion() to update the sprite coordinates and possibly the cursor.
However, if we left the surface with a button down, it means the wayland
compositor has grabbed the pointer so we will not get button release
events from the compositor.
Once the button is released, Xwayland will get a pointer enter event from
the compositor, and Xwayland will clear up the buttons pressed.
But that might confuse Xwayland in thinking the pointer has crossed the
windows and leave the wrong cursor showing in the X11 surface.
To avoid the issue, if buttons are down, do not pretend the cursor has
left the X11 surface for the root window.

The WriteReplyToClient() macro is used for cases where byte swapping
is implemented in a separate callback function (set in a global vector

byte swapping directly in it's request handlers, there's no need to
call the WriteReplyToClient() macro - we can use WriteToClient() instead.
