Thanks.  No more crashes.  It now behaves IIRC as with the NS builds
where child frames can be freely moved around the root frame or display.
On a GTK GUI frame they become invisible whenever they leave their
parents' rectangles.  I won't object your choice but maybe someone else
will.

I didn't fix that yet.  What's needed here is to accumulate the sizes
and/or positions of all ancestor frames.
