Only for a jump scroll. When dragging or scrolling by page, PORTION passed to x_send_scroll_bar_event is zero, as is WHOLE.
For jump scroll, PORTION is the position of the scroll bar thumb that we jump to.
The values of PORTION in x_send_scroll_bar_event and x_set_toolkit_scroll_bar_thumb are different. The first has values as defined by the scroll bar. For Gtk+, Motif and Xaw this is a value between 0 or 1 and 10000000.
The values to x_set_toolkit_scroll_bar_thumb are in characters, i.e. show PORTION characters for the buffer, starting at character POSITION. The buffer has a total of WHOLE characters.
