Bridges and Overpasses

Aug 24, 2007: Demonstration of a new feature under development for 3.0.  New tricks in TrackLayer will allow you to set up clipping regions and specify which tracks go above and below.

Aug 27: Revised version showing precision clipping at tunnel entrances.  Also providing a glimpse at the underlying data.  Also showing new style of turning via simulated trucks -- these are set to 100% wheelbase, but the value is adjustable.
