I don't agree.
GetRulerCoord is used only by the code that is working our how to space
out the graticules on the ruler, how to draw them and how to label them.
It has no effect on redraw rectangles at all - just on coords shown to
the user within those rectangles.
It is, I admit, untested but it's just a simple extension of the code
that already modifies the displayed coords to take the user-settable
page origin into account and it seems to be doing the intended job to
me. Have you tried it?
