Sure,
Oh, the fixup code didn't have anything to do with Jason. Sorry for the
confusion. The inframe is only intended for the backend, and Jason is a
front-end component, so the fixup code wasn't required for Jason. The
reason I have the fixup code is because I needed a new backend, which
happened to be written in c++.
