Sorry, this cannot work. The UserRect the current tool can modify via
this method is simply the area on screen to be redrawn, so by changing
this rectangle, all the tool can do is prevent some part of the ruler
from being redrawn. The relationship between displayed ruler
coordinates and the page coordinates remains the same.
