a8baa20be8 Make tempo lines physical_screen_height high, add xml null check, Use clicked_regionview directly to calculate region movement. Using drag_info.data may result in the wrong regionbiew being used, don't use canvas coords for region_drag_finished_callback x calculation (eliminates speed adjustment), prevent incorrect updates on dropped regions by updating canvas before placing region copies.

95d82d7a16 An actual tempo line cache (not quite perfect when scrolling left, but miles ahead of the previous one didn't really help at all).
Tempo line updating done immediately/directly rather than in an idle handler.
Looking for feedback how this works for other people, performance wise...
Feel-wise, the obvious lag between scrolling and tempo lines being drawn is now gone.

7c950f279b Pulled tempo line stuff out into it's own relatively self-contained class.
Draw tempo lines on time canvas and connect them up all pretty-like to the ruler ticks.
Still needs some visual tweaking, but... they draw!  Finally!
