Xwayland is usually spawned by the Wayland compositor which sets the
command line options.
If a command line option is not supported, Xwayland will fail to start.
That somehow makes the Xwayland command line option sort of ABI, the
Wayland compositor need to know if a particular option is supported by
Xwayland at build time.
Also, currently, Xwayland is being installed along with the rest of the
common executable programs that users may run, which is sub-optimal
because, well, Xwayland is not a common executable program, it's meant
to be a proxy between the Wayland compositor and the legacy X11 clients
which wouldn't be able to run on Wayland otherwise.
Xwayland would be better installed in `libexec` but that directory is
(purposedly) not in the user `PATH` and therefore the Wayland compositor
may not be able to find Xwayland in that case.
To solve both problems (which options are supported by Xwayland and
where to look for it), add a `pkg-config` file specifically for Xwayland
which gives the full path to Xwayland (`xwayland`) and which options it
supports (using `pkg-config` variables).
The `pkg-config` file also provides the `Version` so the build scripts
can check for a particular version if necessary.
Obviously, Wayland compositors are not required to use the `pkg-config`
file and can continue to use whatever mechanism they deem preferable.

The way Xwayland works (like all Wayland clients), it first queries the
Wayland registry, set up all relevant protocols and then initializes its
own structures.
That means Xwayland will get the Wayland outputs from the Wayland
compositor, compute the physical size of the combined outputs and set
the corresponding Xwayland screen properties accordingly.
Then it creates the X11 screen using fbScreenInit() but does so by using
a default DPI value of 96. That value is used to set the physical size
of the X11 screen, hence overriding the value computed from the actual
physical size provided by the Wayland compositor.
As a result, the DPI computed by tools such as xdpyinfo will always be
96 regardless of the actual screen size and resolution.
However, if the Wayland outputs get reconfigured, or new outputs added,
or existing outputs removed, Xwayland will recompute and update the
physical size of the screen, leading to an unexpected change of DPI.
To avoid that discrepancy, use a fixed size DPI (defaults to 96, and can
be set using the standard command lime option "-dpi") and compute a
physical screen size to match that DPI setting.
Note that only affects legacy core protocols, X11 clients can still get
the actual physical output size as reported by the Wayland compositor
using the RandR protocol, which also allows for the size to be 0 if the
size is unknown or meaningless.

Since the introduction of "modesetting: Remove unnecessary fb addition from
drmmode_xf86crtc_resize" the fb_id isn't initialited at
drmmode_xf86crtc_resize.
Rotate operation of XRandR uses rotate_bo. So in this case the fb_id
associated to the front_bo is not initialized at drmmode_set_mode_major.
So fd_id remains 0.
As every call to drmmode_xf86crtc_resize allocates a new front_bo we should
destroy unconditionally the old_front_bo if operation success. So we free
the allocated GBM handles.
This avoids crashing xserver with a OOM in the RPI4 1Gb at 4k resolution

When the linux-dmabuf protocol is available, prefer it over the old
wl_drm protocol. Previously wl_drm was used when modifiers aren't
supported, however linux-dmabuf supports formats without modifiers too.
In this case, linux-dmabuf will send a DRM_FORMAT_MOD_INVALID modifier
for each supported format [1].
This allows compositors to better handle these buffers, getting a
DMA-BUF and implementing features like direct scan-out.
A similar logic has been implemented for EGL [2].
DRM_FORMAT_MOD_INVALID is now stored in the xwl_screen->formats list.
glamor_get_modifiers still returns FALSE with zero modifiers if the
only advertised modifier is DRM_FORMAT_MOD_INVALID.

Without this the client library will flail around looking for a default
provider, probably one named "indirect", and that defeats the point of
having the EGL provider for direct context support in the first place.
This assumes that "mesa" will work, of course, and in general it should.
Mesa drivers will DTRT through the DRI3 setup path, and if our glamor is
atop something non-Mesa then you should fall back to llvmpipe like 1.20.
In the future it might be useful to differentiate the vendor here based
on whether glamor is using gbm or streams.

In this pretty Wine/Proton specific kludge, we try to handle confining grabs
on InputOnly windows by trying to find the InputOutput window that the pointer
would get visually confined to.
The grabbing window and the visible window come from different clients, so
we used to simply resort to the pointer focus. This is troublesome though, as
the call may happen very soon at a time that the toplevel wasn't yet mapped by
the Wayland compositor, so the pointer focus may well be out of date soon.
In these situations, it does seem that even though the confining grab happens
too early to have the wayland surface mapped, the xserver view of the WindowPtr
does already reflect the size. Use this to find out the better window to
assign the confining grab to, one whose geometry fully contains the InputOnly
window's.

When an X11 client has an active grab on the pointer, all events are
reported relative to the window with the grab.
For Xwayland, if an X11 client has a grab with a pointer confinement
active, while pointer focus is on another window, motion events should
not be reported to the client with the grab, because that sets the X11
client appart, the events would be reported when the pointer is on any
X11 window but not on Wayland native surfaces.
Therefore, if the pointer is confined on a window and that window
differs from the actual pointer focus window, just pretend we lost
pointer focus to another window.

If a client issues a grab on the pointer while the cursor is on another

onto that other window.
Then a button click might end up moving the focus away from the window
which issued the grab, leaving the whole setup in a mixed up state.
Typically, if the pointer is on another X11 window, we should not try to
lock the pointer, so that it can be moved back to the window which
actually issues the grab (and hence the pointer confinement). Typically,
this is the same as an X11 client issuing a pointer grab while the
cursor is on another Wayland native window.

Mutter recently added headless tests, and when running those tests the

Xwayland is spawned by the Wayland compositor and upon startup will
query the various Wayland protocol supported by the compositor.
To do so, it will do a roundtrip to the Wayland server waiting for
events it expects.
If the Wayland compositor terminates before Xwayland has got the replies
it expects, it will loop indefinitely calling `wl_display_roundtrip()`
continuously.
To avoid that issue, add a new `xwl_screen_roundtrip()` that checks for
the returned value from `wl_display_roundtrip()` and fails if it is

Convert clipboard integration code from libX11 to xcb
This drops support for COMPOUND_TEXT. Presumably some ancient
(pre-2000) clients exist which support that, but not UTF8_STRING, but we
don't have an example to test with. (Given the nature of the thing, the
users of those clients probably work in CJK languages)
Supporting COMPOUND_TEXT would also involve writing (or extracting from
Xlib) support for the ISO 2022 encoding.

Fix the length of text property set by a SelectionRequest
The length of the text property is not neccessarily the same as the
length of the clipboard text before it is d2u converted (specifically,
if that contains any '\r\n' sequences, it will be shorter as they are
now just '\n')
Always use CF_UNICODETEXT clipboard format. Windows will automatically
down-convert to CF_TEXT for clients which request that.
This is subtly different in one way: if CF_TEXT is requested, we now
post CF_UNICODETEXT and it is converted to CF_TEXT *in the locale of the
requesting process*. Previously, we would convert to CF_TEXT *in our
locale* and post that.
It looks like the code in the !X_HAVE_UTF8_STRING case didn't actually
work correctly, but fortunately that has never been true...
The original Win32 clipboard API is widely regarded as terrible, since
it relies on clients co-operatively managing the clipboard viewer chain,
and a single buggy client can break it for all other clients.
The last Windows version only supporting that API was Windows XP (5.1),
EOLed in 2014.
