Sorry about forgetting to reply to the list when I asked you if you
wanted to edit images in C source code.
Since I know that's not what you want to do, I'll ask, have you
considered asking your questions on the developers lists?
I just searched the web using google for "gimp developers" and got
back a list of stuff you might be interested in, including the url of
the gimp developers mail list archive and the gimp gui developers mail
(If you ask about your toggles on the gui mail list, it may be the
only question for October. )
I think your already found the GIMP wiki and FAQ.
Perhaps the other links of immediate interest to you will be the
mailing lists page where you can find the developers and GUI lists,
and the GIMP from source link. But that's just my guess.
I don't think many of the subscribers to the users list here will be
able to answer your questions, so do ask on the developers and GUI
