operator correctly. You should look-up this in the Red Book: the 2nd parame-
ter is not number of values in the array of the first one, but an offset
into this description of the pattern. I mean a real *offset* not index
into array. I.e. If the command is [3 4] 1 setdash is used, then there
will be first black line *2* units long, then space 4 units, then the
pattern of *3* units black, 4 units space will be repeated.

// 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
// and also the descender. this may be improved, but for now
// 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();
// long w,h;
// dc.SetFont(new wxFont(10, wxROMAN, wxNORMAL, wxNORMAL));
// dc.GetTextExtent("Hallo",&w,&h);
// dc.EndPage();
// dc.EndDoc();
