    <!-- ***** MEASUREMENT CONVERSIONS *****

     * 1 centimeter = 10 mm

     * 1 inch = 25.4 mm
        While the English have already seen the light (read: the metric system), the US
        remains loyal to this medieval system.

     * 1 didot point = 0.376065 mm
            The didot system originated in France but was used in most of Europe

     * 1 pica point = 0.35146 mm
            The Pica points system was developed in England and is used in Great-Britain and the US.

     * 1 PostScript point = 0.35277138 mm
            When Adobe created PostScript, they added their own system of points.
            There are exactly 72 PostScript points in 1 inch.

     * 1 pixel = 0.26458333.. mm   (by 96 dpi)
            Most pictures have the 96 dpi resolution, but the dpi variable may vary by stylesheet parameter
    -->

    <!-- OPTIONAL: DPI (dots per inch) the standard resolution of given pictures (necessary for the conversion of 'cm' into 'pixel')-->
