If there's no available window buffer.
This allows keeping xwl_window_buffer->damage_region empty for a newly
allocated xwl_window_buffer in xwl_window_buffers_get_pixmap, instead
of first populating it in xwl_window_buffer_add_damage_region and then
emptying it again.
Assuming the same number of window buffers, this results in one less
pixmap per toplevel window, saving pixmap storage.
v2:
* Preserve xwl_window_buffer_get_available behaviour (Olivier Fourdan)
v3:
* Leave RegionEmpty call where it was in xwl_window_buffers_get_pixmap,
so it takes effect for a newly allocated struct xwl_window_buffer.
* Consolidate xwl_window_buffer->pixmap assignment in the same place.
Use xwl_window_buffers_dispose instead. The pixmaps will need to be
re-created anyway, so keeping around the xwl_window_buffers doesn't
buy much. And dropping this makes the next commit simpler.
Also fold xwl_window_buffer_destroy_pixmap into its only remaining
caller, xwl_window_buffer_maybe_dispose.
v2: (Olivier Fourdan)
* Fix up indentation in xwl_window_set_window_pixmap
* Leave xwl_window_buffer_destroy_pixmap helper

A clip should represent the area that is covering the current FB associated
with the CRTC. So making sure each input rect covers any area in the FB is
the first thing to do. If that is the case, the size and coordinates should
be adjusted based on the partial area in the FB the each rect covers. The size
elements need to be truncated if the rect's size exceeds FB's for the CRTC.
Then offsets should be applied to coordinates if the CRTC's offsets aren't 0.
And coordinate transposing and inversion are needed in case the rotated image
is assigned to the FB.

Try to minimize the used hw cursor size in order to
minimize power consumption. There is no kernel query
for the minimum so we'll just probe around with
setcursor2 (using an invisible cursor image so
there will be no visual artifacts).
To avoid having to deal with absolutely every size stick
to power-of-two numbers. And with a bit of extra effort
we can determine whether non-square dimesions will also
work, which they do to some degree on current Intel GPUs.
On my Alderlake laptop I'm seeing a massive (up to .5W)
difference in power consumption between 64x64 vs. 256x256
cursors. While some of that is undoubtedly something that
needs to be fixed in i915's display data buffer allocation
code, it still makes sense to use as small as possible
cursor to minimize the wastege.
In case the crtc is rotated just punt to the max cursor size
for now since midlayer has already done the coordinate
transformations based on that. To make smaller cursors work
with rotation we'd either need to make the midlayer(s) aware
of the final cursor size, or just handle the whole roation
business in modesetting. I suspect the latter option would
be easier.
v2: Only allow square cursors in most cases for now as eg.
on modern Intel hardware non-square only works with
wide+short but not with narrow+tall cursors. Non-square
size may still be used when maximum limits aren't
square and the squared+POT'd dimensions would exceed
one of the max limits.

Make sure we're not scanning out any fbs with fancy modifiers when

where the screen gets resized, but in cases where that doesn't happen

X11 clients tend to assume that pointers have buttons. This
assumption means they often fail to handle the X error that
is generated when querying the button mapping of a pointer
device that lacks buttons.
This failure to handle the X error leads to those client
applications to abruptly exit.
This commit assigns vestigial buttons to the gesture pointer
device for the sole purpose of backward compatibility with
legacy X11 clients.
That technique is already employed for a different pointer,
the relative pointer device, for similar reasons, so this
just makes the legacy client compatibility more complete.
See https://gitlab.gnome.org/GNOME/mutter/-/issues/2353
When creating the output with the default "XWAYLAND<n>" name, we use
the MAX_OUTPUT_NAME value to allocate a lot more memory than necessary
to accommodate for future output names once they get updated, but by
doing so, we also send XRandR way too much (zeroed) data since the
"nameLength" value is (purposely) set too big.
So, instead, let's just update the name after creating the RR output,
this way we set both the name and nameLength to their correct values
while keeping the initial large allocation.

Fixes: 3c07a01c42 - xwayland: Use xdg-output name for XRandR
Reviewed-by: Simon Ser <contact@emersion.fr>
At creation, Xwayland uses a generic output name ("XWAYLAND0", etc.) for
the XRandR outputs, and later, once the name is known from the Wayland
protocols, updates the output names using the actual names from the
Wayland compositor.
However, when doing so, it simply updates the string, the "nameLength"
isn't updated, so the name passed to the clients might either end up
being truncated or contain portions of the previous (initial) output
name.
Note, this is using a fixed size buffer initialized with zeros, so this
cannot leak any data other than the previous output name, so this is
mainly a cosmetic issue.
Update the output's "nameLength" when updating the output name.

Xwayland offers a way for the window and compositing manager to hold the
surface commits through an X11 property _XWAYLAND_ALLOW_COMMITS.
Xwayland, however, does not actually check if the X11 client changing
the value of that property is indeed the X11 window manager, so any X11
client can potentially interfere with the Wayland surface mechanism.

When running fullscreen, if an X11 client has changed the resolution,
Xwayland is using a viewport to emulate the expected resolution.
When changing focus, the Wayland compositor will send a configure event
with the actual surface size, not the size of the emulated XRandR
resolution.
As a result, changing focus while XRandR emulation (and hence the
viewport) is active in Xwayland will revert the resolution to the actual
output size, defeating the XRandR emulation.
To avoid that issue, only change the size when not running fullscreen.
