When a drag and drop occurs from an X11 client to a Wayland native
client, mutter uses an internal X11 window as a peer for the DnD drop
site.
That internal X11 window is moved and resized to match the Wayland
native windows as the drag destination moves.
When moving from one Wayland native window to another Wayland native
window, the same X11 window is used, and as a result no DND enter/leave
events is emitted.
In that case, the drop may occur on the wrong Wayland native window,
because no new XdndEnter/XdndLeave event were emitted.
To avoid that issue, use a pair of X11 windows instead of just one and
alternate between the two when repicking a new drop surface, so that
moving from a Wayland surface to another will always generate the
expected enter/leave events that we rely on.

When generating the action label, we expect both directions of these
features to have consistent settings (either both get a keycombo, or
they don't) or these just return NULL altogether.
Since one of the directions has an action associated, this is
misleading, so be more lenient at the time of generating the action
label.

The distribute_natural_allocation() function was copied over from Gtk to
Clutter 11 years ago with commit e636a0bbce.
Gtk only supports integers sizes in its layout machinery, while Clutter
does everything using floats.
Since this function sets the minimum_size (the size we allocate the
children in the end) to an integer, this means we're implicitly
typecasting floats to integers here, effectively floor()'ing all sizes
that we allocate the box children.
A bug this caused in gnome-shell was that a scrollView (like the one in
the endSessionDialog) was showing scrollbars even though the content
perfectly fit inside the view: Say the content and its scrollView parent
request a size of 63.9 px, but get allocated a size of 63 px by a box
layout. Now the scrollView notices that its allocated size is smaller
than the requested size and thus shows a scrollbar.
So fix that and use floats in distribute_natural_allocation() instead of
integers, as we do everywhere else in the layout machinery.

If we happen to handle a CLUTTER_TOUCH_BEGIN without a corresponding
CLUTTER_TOUCH_END at MetaWaylandTouch, we would still attempt to
reuse the older MetaWaylandTouchInfo, resulting in an assert triggered
as there is a stale touch reference on the previous surface.
Warn in place and create a new touch info struct to still fix the
broken surface accounting, instead of finding out the hard
way after the surface is destroyed. The assert is preserved to ensure
the accounting does not sneakily break anymore/further.

It passes a MetaLogicalMonitor, which isn't introspected right now, so
skip it completely. The entry point to the UI is handled via
MetaDisplay, so it isn't needed.
This fixes the following warning:
<unknown>:: Warning: Meta: (Signal)monitor-privacy-screen-changed: argument object: Unresolved type: 'MetaLogicalMonitor'

Structure tests in a list of dictionaries, instead of requiring each
test to have its own executable(...) and test(...) statement. The
intention of this is to make it easier to add more test cases.

It already was built into it without any symbols exported, but also
duplicated in test cases that used it. Make it so that the built in
functions are exported, with prefixes, and make all tests use the
exported functions. While at it, make things go via MetaContext or
MetaBackend depending on how early in initialization things are run.

We update some details like the last used device and pointer visibility
from events, but this is done inconsistently on X11 since the
ClutterEvents are created and pushed from an additional place.
Make these updates happen on a private call, that will be called from
these places in X11.

Even though it's great that XI2 has an event to notify about device
changes, this is something we can let the MetaBackend code handle
consistently for all backends, since looking for the source device
works everywhere.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/285>
Instead of relying in the device being updated from different parts of our
machinery for different backends, hook this up to our own event dispatching.
This will allow dropping all other places where this is done.
