Reimplement the narrowed hot zone for vertical ruler...

Browse Source 
... Don't define the TrackPanelCell to be narrower.  Instead, change its
hit-test routine, and only if it is a Wave track.

Previous implementation had the unintended consequence, that a click in the
area excluded from vertical zooming was treated as a click on the background
outside of all tracks, causing de-selection of all tracks.
