Arguments: from-window-or-screen to-window-or-screen position-or-box
Converts a position or a box that is in window units relative to from-window into window units relative to to-window. The position or box is destructively modified and returned.
Window units are measured in pixels rightward and downward from the interior upper left corner of a window. (Stream units, on the other hand, are measured from the origin of the conceptual "page" or "canvas" that is scrolled within a window, and may be scaled arbitrarily.)
