[script] Allow setting the position of the windows

Although the windows are set up to in a reasonable default configuration, the
themes may align the windows differently to not crop some important elements.

The Window.SetX and SetY allow positioning the window anywhere on the canvas.
Use this sparingly as it induces a full refresh of all screens.

If there is a desire to have totally different scenes, the second window can be
positioned somewhere far away so there is overlap and a complete different set
of sprites is used. Another sensible configuration is to have the screens side
by side and allow sprites to span the gap. Remember to create password dialogs
for each screen as not all may be visible.
