Two steps:
1. Design the feature: how would it work? which operations would
bring point back into the viewport, and which won't? For
example, a simple question: if point is outside of the viewport,
what is the effect of C-f or C-n on display?
2. Go over the display-related code and modify all the places which
assume point is or must be visible. Source files involved are
xdisp.c, dispnew.c, window.c, fringe.c, probably also indent.c.
IMO, it's a large job if done cleanly. Patches welcome.
