When a cursor is specified in gdk_seat_grab(), the cursor is reverted as
soon as the pointer enters or leaves another window.
To avoid this issue, store the grab cursor separately, so we force-apply
it in ::set_window_cursor(). Also, unset early the seat info from the
window on gdk_seat_ungrab(), so the next time switch_to_pointer_grab()
happens we end up picking the cursor set for the window underneath the
pointer window.
Based on a patch by Olivier Fourdan <ofourdan@redhat.com>.

We are getting the mime data destroy notify called when we
destroy the surface in finalize. Trying to set the XSync counters
at this time is a) pointless and b) yielding an X error because
the counters have already been destroyed.
To avoid this, unhook the damage tracking before destroying
the surface.

We are setting mime data with a destroy notify on the cairo
surface to get notified when cairo registers damage for the
surface (in that case, it clears the mime data, calling the
destroy notify). Unfortunately, the destroy notify is also
called when we remove the mime data ourselves, which was
not intentional.
Use a flag in the window impl struct to ignore the callback
when we are clearing the hook.
Instead of creating an intermediate pixbuf, just render
the window surface onto the new surface. Doing things this
way lets us avoid the cairo_surface_mark_dirty() call in
gdk_pixbuf_get_from_window(), which is not generally safe
to call on 'random' surfaces - it asserts that the surface
has no mime data attached, and the X11 backend uses mime
data for damage tracking purposes...
We destroy the widget that is wrapped around the drag window
when the object data on the drag context gets cleared. Destroying
the window before that happens leads to unpleasantries. E.g. we may
try to access the frame clock, which doesn't exist anymore, and
things go downhill from there. So, keep the window alive for
a little longer.

X11 has the notions of "transient for group", and while it's an ICCCM
violation, it's commonly used and documented that a window manager
would treat a window with transient_for set to None to transient for all
windows of its group.
gtk uses this when an application sets a dialog type window but does not
specify an explicit transient.
While this works on X11, there is no such thing as groups in Wayland and
the closest equivalent which is set_parent() in xdg-shell takes only one
parent. This is what is used for modal dialogs.
To get something similar in behavior to what is available on X11, a
solution is to update the parent() of the dialogs without transient when
the active surface changes.

Quite a few applications use GTK_WINDOW_POPUP to create various
temporary windows and place then on screen. That works fine on X11 but
on Wayland there is no global coordinate system for regular surfaces.
If the application is using a gdk temp window and set a parent with
gtk_window_transient_for(), the gdk wayland backend has all it needs to
create a subsurface that can be placed at will by the application.

Always returning a left_ptr if we can't find anything better
broke firefox application-specific fallback for missing cursors.
Keep that working by only doing the fallback for the CSS cursor
names, not for things like hashes.

Functions requiring CoInitialize are called just in two places:
- the filechooser thread which calls its own CoInitializeEx
- the dnd code
Moving CoInitialize in the dnd specific init is cleaner and
we can pair it with the corresponding CoUninitialize since
CoUninitialize should be called as many times as CoInitialize.
Note that it is ok to call this function multiple times, so it
will not break if another codepath will need it in the future.
The patch also replaces the deprecated CoInitialize with the
equivalent call to CoInitializeEx (already used in the filechooser).
In most places, we can do with the pointer/keyboard of the default seat
instead of the client pointer. We can also remove some code from
gdk_input_init() because we know for sure there's no floating devices to
care about here.
There's places where we still need to deal with floating devices, which are
unseen by seats. Ignore deprecations and keep using GdkDeviceManager until
we can forget about floating devices.

There's places where we don't set a seat yet, plus the places
outside GTK+ where events are created, we should warn and fall
back to the master device seat with these.
Gdk Wayland backend walks up the transient windows tree, but does not
check for cycles when doing so.
As a result, if two or more windows are transient to each other, the
Wayland gdk backend will enter an infinite loop.
While this is clearly a bug in the application, gtk+/gdk should be more
robust and handle such errors more gracefully.
To avoid looping infinitely at various point in the code, check for a
possible loop when setting the transient relationship and deny the
request to set a window transient for another if that would create a
loop.

gdk_pixbuf_get_from_window() paints the given window onto a new cairo
surface. Create that new surface with the same device scale as the
window so that the result is not scaled down on hidpi screens.
This is similar to 657a43e (which was reverted), but doesn't modify the
behavior of gdk_pixbuf_get_from_surface().

Our actions on ::device-removed only actually applied to master
pointers, so listening to GdkDisplay::seat-removed and operating
on the seat pointer is equivalent.
