Prompt in Tk interface

[Bas de Bakker]

In extras/graphics/README there's a question about avoiding the tcl
prompt.  It seems to me you can do this by calling Tk_MainLoop (the
"real" main Tk routine) directly, instead of calling Tk_Main, which as
I understand it is more of an example main routine.

This means you'd have to do some more initialization yourself, but
this could easily be done by copying Tk_Main from the Tk sources and
removing the unnecessary stuff (like creating the prompt and handling
input).

At the same time you could consider removing the callback mechanism
(which seems mainly there to allow the client code to use the
interpreter created by Tk_Main) and creating something like
mtcltk__create_interp(tcl_interp::out) to create an interpreter and
then after the client code creates commands, windows and such it can
call a mtcltk__mainloop predicate.

P.S. I'm new here, is this appropriate for this list, or should I have
sent it to the mercury team directly?
