1607 / CAVE: the size of the string is currently always calculated
1608 / in 'points' (1/72 of an inch). this should later on be
1609 / changed to depend on the mapping mode.
1610 / CAVE: the path to the AFM files must be set before calling this
1611 / function. this is usually done by a call like the following:
1612 / wxSetAFMPath("d:\\wxw161\\afm\\");
1613 /
1614 / example:
1615 /
1616 / wxPostScriptDC dc(NULL, TRUE);
1617 / if (dc.Ok()){
1618 / wxSetAFMPath("d:\\wxw161\\afm\\");
1619 / dc.StartDoc("Test");
1620 / dc.StartPage();
1621 / long w,h;
