This is currently just used as a convenience storage of the startup ID
between the GtkApplication and the GtkWindow (after it's ready to notify
on it).
This could be untangled in the GTK layers so there is no involvement
from GDK in keeping the startup ID around, in the mean time just deprecate
these gdk_wayland* API calls.
These pieces were added in commit 8d2f81cca4, but are no longer
necessary since there's no capture_button_press special behavior
toggle.
This can be simplified again.
Do not get a GdkEvent first and foremost, and only do that in the
parts where the GdkEvent is absolutely necessary (i.e. popping up
the WM menu for the window).
We can abstract widgets about the specific ongoing sequences that
are triggering a GtkGesture. This used to be more necessary in
GTK3 world where complex widgets might have required handling
different events in different areas, but in GTK4 world that would
be done with multiple widgets.
This is no longer necessary to carry forward.
It does not require special knowledge about the ongoing event
sequences, and it can instead trust the event controller. Make
it use gtk_gesture_set_state() generically.
The design patterns using statusbar are no longer popular,
and it is pretty easy to make a statusbar yourself with boxes
and labels, if you need one. The only thing special about
GtkStatusbar was its window resize handle, but that has
been gone for a long time.
Set the label to expand, so it actually fills
the width that we allocated for it, instead
of shrinking back to the minimum width for
its height.

Setting max-width-chars to the number of characters
in the string works ok only as long as the average
char width we get from Pango matches reality. Sadly
that seems not always the case, and this code was
causing short Chinese tooltips to always be broken
into two lines.

At the moment, GTK applications search for "desktop-startup-id" in the
platform data on Wayland , but desktop environments such as plasma set
"activation-token" property instead as indicated in the spec:
activation-token: This should be a string of the same value as would
be stored in the XDG_ACTIVATION_TOKEN environment variable, as specified
by the XDG Activation protocol for Wayland.

The idea behind this code was to let scalable
images (i.e. mainly SVGs) provide twice as much
detail when the scale is 2. But we were also
using a scaler for pngs, causing them to be too
small on a hidpi screen. Fix that.
Note that there are cases where you want scaling
for pngs (when you display them scaled down, so
the image has 'hidden' detail). But we are not
attempting to handle that situation automatically.
Escape XML tags in gi-docgen oriented comment e.g. from <child> to
`<child>`, so that they don't become HTML tag on the final webpage.
This fix includes everything from commit ff46ea64 and #5312.
