Sure, good idea.
I'm working into lwlib only. So I've made a function to get the frame
of the menu widget (mw). I'm also converting the char* display_string
of each menu entry to a Lisp_String with make_string (note: I don't know
if I should have done that but it seems the way to get a proper
multi-byte string from a char*).
Finally, I'd like to walk this Lisp_String and call FACE_FOR_CHAR for
each charater of this frame. And then be able to call XftDrawStringUtf8
(or XmbDrawString) on each substring/font pair. WDYT?
