Darin Adler,

Thank you for taking a stab at this on a weekend day.

You are right, the paintTickmarks call doesn't need to be specific to the
vertical scrollbars. We (Chromium) don't want the tickmarks for horizontal
scrollbars, but that doesn't mean others wont. I have removed that check.

I also removed paintTickmark (singular). I thought it might make sense to
provide guidance for the implementors of the tickmarks (for a given port), but
you are right: we don't need that in the base class.
