/* method for calculating string widths in postscript:
/ read in the AFM (adobe font metrics) file for the
/ actual font, parse it and extract the character widths

/ it works well. the AFM file is only read in if the
/ font is changed. this may be chached in the future.
/ calls to GetTextExtent with the font unchanged are rather
/ efficient!!!
/
/ for each font and style used there is an AFM file necessary.
/ currently i have only files for the roman font family.
/ I try to get files for the other ones!
/
/ 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\\");
/
/ example:
/
/ wxPostScriptDC dc(NULL, TRUE);
/ if (dc.Ok()){
/ wxSetAFMPath("d:\\wxw161\\afm\\");
/ dc.StartDoc("Test");
/ dc.StartPage();
/ wxCoord w,h;
/ dc.SetFont(new wxFont(10, wxROMAN, wxNORMAL, wxNORMAL));
/ dc.GetTextExtent("Hallo",&w,&h);
/ dc.EndPage();
/ dc.EndDoc();
