    - bug 9984, fix embedded bonobo objects a starting size > 0,0
    - vertical justification was broken
    - a few warnings.

	* src/cell-draw.c (cell_draw) : Cache the vertical alignment, and
	  ensure that verticaly justified lines do not overlap.
	* src/print-cell.c (print_cell) : Ditto.

	* src/sheet-object.c (sheet_set_mode_type_full) : Add a prototype to
	  avoid warnings.

	* src/sheet-object.c (create_object) : Ugly workaround for bug 9984.
	  Ensure that objects do not start with size 0,0.
