| Just keep it simple and keep the focus where it was. I don't think anyone but the user should decide where focus is. I insist - don't copy matlab on this.

I also find that applications that move the focus to be very annoying,
so let's not copy this by default.  If people really want this
feature, then let's make it configurable and NOT the default.

It appears that the place to deal with this is in the graphics handle properties.  There
are already properties like: selected, visible, xdisplay, ...  They appear not to do much
at present.  I remember that when I was "documenting" these for the interpreter Manual,
I just listed them without explanation since I could not find what they did.   More work to
do...

One suggestion: it might be user-friendly to provide a "window manager" window.
This could be created on the first instance of a graphics handle.  This window could have
an entry to each current graphics handle and allow setting the  properties of each window.
(The command window is not a graphics window, so it is a special case.)
