Issues fixed here:
Middle click drag was sending the timeline to 00:00:00,0. I made some changes so that it works relative to the timeline's original position.
The ruler draws a time on every other mark. As you scroll left, it was always starting with the second mark on screen, breaking up the continuous motion of the ruler. I made sure that the ruler always draws times on the same marks, so the scrolling feels continuous.
If you resized the timeline in some way, the ruler wasn't redrawing until you scrolled or zoomed. I added
element.width()
to the watched variables that callsdrawRuler
, so that this now causes the ruler to redraw.
