    // resolution which is 72 dpi (probably inspired by Postscript).
    // 2 - To have a sufficient resolution, this is increased by 16 times,
    // by using the scale method of the graphic object associated to the
    // printer. This gives a 72 dpi * 16=1152 dpi resolution.
    // 3 - The 0.127 mm pitch used in FidoCadJ corresponds to a 200 dpi
    // resolution. Calculating 1152 dpi / 200 dpi gives the 5.76 constant
