1722 / font is changed. this may be chached in the future.
1723 / calls to GetTextExtent with the font unchanged are rather
1724 / efficient!!!

1726 / for each font and style used there is an AFM file necessary.
1727 / currently i have only files for the roman font family.
1728 / I try to get files for the other ones!

1730 / CAVE: the size of the string is currently always calculated
1731 / in 'points' (1/72 of an inch). this should later on be
1732 / changed to depend on the mapping mode.
1733 / CAVE: the path to the AFM files must be set before calling this
1734 / function. this is usually done by a call like the following:
1735 / wxSetAFMPath("d:\\wxw161\\afm\\");
1736 /
1737 / example:
1738 /
1739 / wxPostScriptDC dc(NULL, TRUE);
1740 / if (dc.Ok()){
1741 / wxSetAFMPath("d:\\wxw161\\afm\\");
