Re: kpfonts, math, type 1 font

[Elspeth McGullicuddy <elspethmcgullicuddy@gmail.com>]

As for the point: "bold uppercase greek letters aren’t mapped" I've inserted
the following at the beginning of file "pkfonts-math.lfg":
(I put the whole file it'll be easier to understand)
=> capital greek are not showing though

I've mimicked the file "lucida-typeone-math.lfg".
