RELATIVE work at the moment only for BUTTON. INPUT and OUTPUT use other systems:
set this gadget relative to a windowborder!
i.e. output X=5 Y=5 W=-5 H=-5 RELATIVEH RELATIVEW
will setup the outputgadget to be 5 pixels away from each windowborder.
But: the resizing works typical only for the right and bottom border. Why?
because you in/decrease window on the lower right corner.
