* nsISelectionController).
* @param aIsSynchronous - when true, scrolls the selection into view
* before returning. If false, posts a request which
* is processed at some point after the method returns.
* @param aVPercent - how to align the frame vertically. A value of 0
* means the frame's upper edge is aligned with the top edge
* of the visible area. A value of 100 means the frame's
* bottom edge is aligned with the bottom edge of
* the visible area. For values in between, the point
* "aVPercent" down the frame is placed at the point
* "aVPercent" down the visible area. A value of 50 centers
* the frame vertically. A value of -1 means move
* the frame the minimum amount necessary in order for
* the entire frame to be visible vertically (if possible).
* @param aHPercent - how to align the frame horizontally. A value of 0
* means the frame's left edge is aligned with the left
* edge of the visible area. A value of 100 means the
* frame's right edge is aligned with the right edge of
* the visible area. For values in between, the point
* "aHPercent" across the frame is placed at the point
* "aHPercent" across the visible area. A value of 50
* centers the frame horizontally . A value of -1 means
* move the frame the minimum amount necessary in order
* for the entire frame to be visible horizontally
