I'm currently trying to set up horizontal scroll bars so please help me
clarify this issue.  The comment of x_set_toolkit_scroll_bar_thumb says

/* Set the thumb size and position of scroll bar BAR.  We are currently
    displaying PORTION out of a whole WHOLE, and our position POSITION.  */

That of x_send_scroll_bar_event says

/* Send a client message with message type Xatom_Scrollbar for a
    scroll action to the frame of WINDOW.  PART is a value identifying
    the part of the scroll bar that was clicked on.  PORTION is the
    amount to scroll of a whole of WHOLE.  */

So the term PORTION in x_send_scroll_bar_event seems semantically
equivalent to the term POSITION in x_set_toolkit_scroll_bar_thumb and
not to the term PORTION in x_set_toolkit_scroll_bar_thumb.  Is that
interpretation correct?

Thanks, martin
