2202 / font is changed. this may be chached in the future.
2203 / calls to GetTextExtent with the font unchanged are rather
2204 / efficient!!!
2205 /
2206 / for each font and style used there is an AFM file necessary.
2207 / currently i have only files for the roman font family.
2208 / I try to get files for the other ones!
2209 /
2210 / CAVE: the size of the string is currently always calculated
2211 / in 'points' (1/72 of an inch). this should later on be
2212 / changed to depend on the mapping mode.
2213 / CAVE: the path to the AFM files must be set before calling this
2214 / function. this is usually done by a call like the following:
2215 / wxSetAFMPath("d:\\wxw161\\afm\\");
2216 /
2217 / example:
2218 /
2219 / wxPostScriptDC dc(NULL, TRUE);
2220 / if (dc.Ok()){
2221 / wxSetAFMPath("d:\\wxw161\\afm\\");
