It seems that X11 use short value for drawing string (XDrawString),
for Fl_Tree_Item, it can make problem of drawing labels when x, y overflow
David's workaround was to do:
myi-other_xid = ( w() h() ? fl_create_offscreen(w(),h()) : 0 );
instead, i.e. only create the offscreen surface for the double
buffering of the window if the window has non-zero size. Otherwise,
other_xid is set to NULL.
It looks like *most* other
