 /*
   Place item in cell and take care that multiple items using the same cell do
   not overlap. This method is not yet optimal. It doesn´t use the maximum space
   it can get in all cases.
   At the moment the method has a bug: When an item is placed only the sub cell
   widths of the items are changed, which are within the Y region the item to
   place spans. When the sub cell width change of one of this items affects a
   cell, where other items are, which do not overlap in Y with the item to place,
   the display gets corrupted, although the corruption looks quite nice.
