[cairo] cairo toy: charchart

[Evan Martin]

"To decorate my area at work (I work on international search quality),
I wanted to print out some nice, large Unicode charts. This program
uses Cairo to render a set of codepoints to PNG, Postscript, or PDF."

Unfortunately (and related to my previous mail) it only uses a single
font.  I'll look into improving that at some point, but for now it
suffices to pass the font name to the program depending on which
codepoints you're producing.
