Guess I was mistaken.  Setting max height + width is not the same as setting 
fullscreen.

It depends on your expectations :-).  But I will change fullboth to mean max 
width + height and I will add fullmax to mean "cover the screen" in CVS HEAD.

But I must test it on several window managers with several toolkits so it will 
take some time.

As I recall, this was the initial motivation for fullscreen in the first place.
