Warning...

Properties/function/events related to positioning like Form.X, Form.Y, Form.Move, Form_Move() will not work or give correct information with wayland.

Gambas cannot see the top level window/screen with wayland.
So it considers the applications main Form as the top level window.
This causes problems with events and getting/setting positions will not work as expected as nothing relates to the underlying screen size.

A Form can only be moved reliably with wayland if it is in it's own larger container.
