Its not really the same as Thorsten's idea, but in ardour when you
grab a control point in an automation track, we draw a big text cursor
showing the value of the current position. I guess i am just pointing
out that when using a canvas-style widget, more or less anything is
possible. with ordinary widgets, its much harder.
