    NAME:       XYPOINT (xy)

    SYNOPSIS:   Encapsulation of a (x, y) point
                This class replaces the Windows POINT structure.

    INTERFACE:  QueryX()         - access member fcns
                QueryY()
                SetX()
                SetY()
                ScreenToClient() - take a screen point and convert
                                   it to window-client coords
                ClientToScreen() - take a point in a window and convert
                                   it to screen coords
                InRect()         - return whether point is within rect
