/*
 *   Flags to use when calling the [XY]Moveto functions.
 *
 *  MV_UPDATE  is used when it is desired to change our record of where
 *      the cursor is now located.  Typically this will happen after some
 *      operation such as printing a glyph, or sending graphics.
 *
 *  MV_RELATIVE  means add the value passed to the current position.  This
 *      would be used after printing a glyph,  and passing in the glyph
 *      width as parameter,  rather than calculating the new position.
 *
 *  MV_GRAPHICS  indicates that the value is in GRAPHICS RESOLUTION units.
 *      Otherwise MASTER UNITS are assumed.  If set,  the value will be
 *      converted to master units before processing.  Typically used to
 *      pass information when sending scan lines of graphics data.
 *
 *  MV_PHYSICAL  is used to indicate that the value passed in is relative
 *      to the printers print origin,  and not the printable area,  which
 *      is the case otherwise.  Typically this flag would be used to
 *      allow setting the position to the printer's X = 0 position after
 *      sending a <CR>.
 *
 *  MV_FINE  requests sending graphics data (nulls) to position the cursor
 *      to finer position than can otherwise be achieved.  Typically
 *      only available in the direction of movement of the head on a
 *      dot matrix printer.  This command may be ignored.  It must not
 *      be issued for a LaserJet,  since it will cause all sorts of other
 *      problems.
