+/- geometry offsets don't work under Wayland

[Steve Langasek]

When using the default wayland-based session in Ubuntu 22.04, trying to use +/- to control window placement doesn't work. E.g. the following should give me a gnome-terminal window in the lower-right corner of the screen:

  gnome-terminal --geometry -0-0

It does not; instead it stacks it with a window position just slightly down from and to the left of the previous window.

GNOME-TERMINAL(1) says:

       --geometry=GEOMETRY
           Set the window size as COLSxROWS+X+Y. For example, 80x24 or
           80x24+200+200.

When run under Wayland, only "COLSxROWS" are honoured, "+X+Y" are not.
When run under Xorg, everything works as expected.

I have a script that creates tens of windows and tabs at predefined positions, which now needs manual repositioning.
