Some drivers might not support explicit format modifiers. On these
drivers `gbm_bo_create_with_modifiers()` will fail and the
`gbm_bo_create()` code path will be used instead.
In this case, if the LINEAR modifier is advertised (and the INVALID
modifier is not) add the `GBM_BO_USE_LINEAR` flag.

While we now have support for resize of the root window through
libdecor, we still ignore toplevel configure dimensions when libdecor is
not in use. This ignores user intent in many Wayland servers, and some
xdg_toplevel states when active have strong requirements for adherence
to configure dimensions.
Resize in response to xdg_toplevel configure dimensions like we do for
libdecor configure events.

The upcoming handling of plain xdg_toplevel.configure events will need

(cherry picked from commit 4f869c6eda)
When handling libdecor configure, we first update our xwl output and
screen if dimensions differ from the current xwl_screen, and then commit
a new libdecor frame which acknowledges the xdg_surface.configure event.
If the initial configure events contains non-zero dimensions, we will
update the xwl output before acknowledging the initial configure. As we
attach a buffer and commit the surface when updating the output, this
leads to a protocol error.
Instead, move the surface commit till the end of the configure handler
so it always happens after the ack.

Similar to commit 94deed272 - " xwayland: Use sensible defaults for
rootful size", mark fullscreen mode as fixed so that the actual monitor
layout is not reflected in the single fullscreen rootful window.
Without this, if "-fullscreen" is used without "-geometry", the XRandR
configuration is taken from the compositor via wl_output/xdg-output and
cannot be changed by the X11 clients.

(cherry picked from commit c180eca8ef)
The configure handler in libdecor is triggered any time a new
configuration is received.
According to the documentation from libdecor, an application should
respond to that event by creating a suitable libdecor_state, and apply
it using libdecor_frame_commit().
So we ought to attach a new buffer matching the new size and commit
the Wayland surface.
The actual content of the window does not need to be explicitly
repainted, that occurs through the call to SetRootClip():
xwl_output_set_mode_fixed()
-> update_screen_size()
-> SetRootClip()
-> miHandleValidateExposures()
-> miWindowExposures()
-> miPaintWindow()
This fixes an issue with mutter where maximizing a window and then
switching to another window would sometimes resize the Xwayland window
back to its pre-maximized size, or with Weston where the Xwayland window
would initially show up black until the pointer moves to the window.

The configure handler for libdecor, namely handle_libdecor_configure(),
is where both the content and the decorations get resized (when needed).
If for any reason, the actual size of the Xwayland screen fails to be
updated, we would still appy the expected size rather than the actual
one for the libdecor state.
To avoid this, use the actual xwl_screen width/height for the libdecor
state.

If "-decorate" is used but no "-geometry" is specified, Xwayland rootful
would take its size from the actual Wayland outputs combined.
That is not practical, especially when using multiple outputs, as the
resulting Xwayland window would be much larger than a single monitor.
To avoid that, set a sensible default size for the Xwayland decorate
window, using 640x480 to match what Xephyr does.

glamor ensures that a depth 32 pixmap backing a depth 24 window contains
fully opaque alpha channel values for the window's pixels, so we can
allow this without implicit redirection, saving pixmap storage and
intermediate copies.
This will be needed with the next commit: If a child window completely
obscures a toplevel ancestor of different depth, the child window can
use page flipping only if the depth of the presented pixmap matches that
of the window's backing pixmap, or the former may contain pixel values
which are not suitable for the toplevel window's depth.
It's needed for a depth 24 window backed by a depth 32 pixmap, to make
sure the window's pixels sample alpha as 1.0.
v2:
* Make sure glamor_finish_access doesn't pass in a NULL pointer.
Pass the DrawablePtr directly from glamor_finish_access to
glamor_upload_boxes. This will allow for better results if the window
depth doesn't match the backing pixmap depth.
