Fix mouse event position offset bug.

Browse Source 
Search scroll groups for event delivery from top to bottom rather than bottom
to top.  Overlapping scroll groups still aren't properly supported by the
canvas, but currently all we care about is that the top one gets the event, so
the hscroll group (tempo lines) can be below the hvscroll group (tracks), but
the latter gets events.
