        1.  (Sometimes abbreviated "pt") The unit of
        length for {text} {characters}.  There are six slightly
        different definitions: {Truchet point}, {Didot point}, {ATA
        point}, {TeX point}, {Postscript point}, and {IN point}.
     
        The most commonly used are ATA in the USA and Didot in Europe.
     
        A {twip} is 1/20 of a PostScript[?] point.

        on-screen pointer is positioned over a certain object on the
        screen such as a {button} in a {graphical user interface}.  In
