1719 / and also the descender. this may be improved, but for now

1721 / font is changed. this may be chached in the future.
1722 / calls to GetTextExtent with the font unchanged are rather
1723 / efficient!!!
1724 /
1725 / for each font and style used there is an AFM file necessary.
1726 / currently i have only files for the roman font family.
1727 / I try to get files for the other ones!
1728 /
1729 / CAVE: the size of the string is currently always calculated
1730 / in 'points' (1/72 of an inch). this should later on be
1731 / changed to depend on the mapping mode.
1732 / CAVE: the path to the AFM files must be set before calling this
1733 / function. this is usually done by a call like the following:
1734 / wxSetAFMPath("d:\\wxw161\\afm\\");
1735 /
1736 / example:
1737 /
1738 / wxPostScriptDC dc(NULL, TRUE);
1739 / if (dc.Ok()){
1740 / wxSetAFMPath("d:\\wxw161\\afm\\");
