With Rotate View, each ruler measured document x (or y) along a line
that crossed both axes: its ticks covered only a short stretch and the
numbers bunched up. Each ruler now measures along its own edge in the
canvas's coordinates turned with the view, so it is ticked over its
whole length at every angle, and reads x and y as before at 0°.
