Remove unused geometry setters in Item

Originally, only x, y, width, and height property setters were used. A
bit later "position" and "size" helper setters were added to simplify
code in SurfaceItem sub-classes. It seems like setX(), setY(), setWidth(),
and setHeight() are unused now, so remove them.
