the rulers are just packed into container above the track canvas.

that's a true statement. it used to be that we had a separate canvas
for the marker bars so that we could scroll the tracks vertically
independently of the timeline. but the rulers are widgets packed into
a container above the canvas.

but nick mainsbridge did some great work on canvas scrolling so that
it is done by moving a whole group of items rather than "actually"
scrolling the canvas itself. this enabled him to put the marker bars
onto the canvas, but the widget-ish nature of the rulers keep them off
on their own.
