Arguments: window-or-screen box
Returns box after modifying it to be equal to the exterior box of window-or-screen. The box is relative to the upper-left corner of the "page" of the parent window, or of the screen if there is no parent window. (A "page" is the logical canvas of a window, on which drawing is done and which is sometimes scrollable. So if the parent window is not scrolled, then the box is relative to the upper-left corner of the parent's interior.) The unit of measurement is pixels.
Contrast with exterior, which creates and returns a new box object.
