Place the rulers' origin at the top-left corner of the canvas (screen space) bounding box, and set their scale to the image- space scale along the screen-space horizontal/vertical directions (in other words, measuring a distance using the rulers should give the same results as the measure tool; note that rotation comes into play here only when the horizontal and vertical image or screen resolutions are different, since otherwise the scale is direction invariant.) Make scrollbar step match ruler step under the new behavior.
