Description Paul Pazderski CLA 2019-08-22 18:25:52 EDT 
The paint method of AnnotationRulerColumn is unnecessary inefficient. More details in the change.

The reason I made this a blocker of bug 80089 is that the slowness increase when the range between min and max used annotation layer increases. In case we allow the user to freely set the annotation layer we can get a serious performance problem. (with the old implementation)


@Lars: yes it is a performance ticket again, but that was pure coincidence! Calling me performance master just raise unnecessary expectations. :D
