Kartikaya Gupta ca310383d4 Bug 696319 - Scroll window as needed when soft keyboard is up [r=mfinkle] 
Send an event to scroll to the focused input field when the
soft keyboard comes up. Ensure that this happens *after* the
viewport change event is sent to Gecko, so that Gecko actually
knows that browser viewport is smaller and doesn't just no-op
the scroll request.
