    /  for each font and style used there is an AFM file necessary.

    /  CAVE: the size of the string is currently always calculated
    /        in 'points' (1/72 of an inch). this should later on be
    /        changed to depend on the mapping mode.
    /  CAVE: the path to the AFM files must be set before calling this
    /        function. this is usually done by a call like the following:
    /        wxSetAFMPath("d:\\wxw161\\afm\\");
