Improve scrolling performance for sessions containing hundreds of regions over many tracks by hiding offscreen tracks (scroll faster by making tracks larger, exposing fewer of them). Use distance from screen edges to drive autoscrolling distance. Avoid using canvas coordinates for displacement calculations where possible. Don't redisplay tempo in the colour handler.
