        * src/print.c: Remove all bonobo-related stuff.
        (print_sheet_objects): New. Prints all objects that overlap a given
        range and clips to that range.
        (print_page_cells): Call print_sheet_objects from here.
        (print_page_object): Removed.
        (print_page): Check for sheet objects if no printable cells can be
        found.
        (render_sheet_objects): Removed.
        * src/sheet-object-bonobo.c (sheet_object_bonobo_print): Move the
        bonobo printing stuff in here.
        * src/sheet-object-impl.h: The virtual method print now has only
        three arguments: The PrintContext and the base (x & y) where to
        start printing.
        * src/sheet-object.[c,h]: Adjusted to new syntax.
        * src/sheet-object-cell-commend.c (cell_comment_print): Same here.
        * src/sheet-object-graphic.c (sheet_object_graphic_print): And here.
        Fixed some broken logic. Printing of arrows implemented.
        (sheet_object_filled_print): Fixed.
        * src/sheet.c (sheet_col_get_distance_pts): Make sign double like in
        sheet_row_get_distance_pts. This didn't fix my problem but it is
        nicer this way (problem got fixed by Jody's fix below).
