[sugar] Any good example of Pango?

[Yoshiki Ohshima]

  Hello,

  I've been trying to implement a multi-font, multi-color,
multi-language text editor-like thing with Pango.  (Actually, it is a
Squeak binding for Pango, but it is besides the point.)

  Is there a working example of editor (in any programming language)
that I can look at and steal the code?

  Thank you!
