FLUD: This fixes the problem that the children of a Widget_Class_Type are positioned with absolute coordintes. The patch adds another button to the FLUID interface named 'Relative' to the right of the widget position. It is only visible if a Widget_Class_Type is selected. If checked, code will be added that creates an Fl_Group at 0, 0 and later repositions it and all its children into the final position.
