David Robillard b87ca000f8 Merge all the (disconcertingly missing) track/region/etc height changes from 2.0.
Fix track y positioning and initial region size/location.
Fix automation click-to-add-points (i.e. points actually show up where you click).
Fancy whiz-bang dynamic resize 2.0 professional edition support for MIDI/CC/Automation tracks/regions.
