Great! :-)

Yes, plus it must also fix pointers to interesting objects, which
mark_frame doesn't need to do. LIke you did with the font.
(Some objects I ahve also moved to MPS, which were previously malloc'd,
itree_tree for examole, but I think I got these covered already
(itree_node, for example.))

Basically yes. The address of the fields is only needed because MPS_FIX2
can give us a new address, which we then have to store where the
reference comes from.
(Consider your change pushed in 1s :-).
