object: total_size, page_size and start_position (e.g.
number of lines, number of lines in one page and the index
of the first line currently displayed).
EZ_DoScroll scrolls the object which scrollbar controls
by the specified offset. If absoulte is True, offset is
treated as the absolute position, otherwise, it is inter-
preted as the offset from the start_position.
