Requiring full-screen repaints is an architectural design that might need 
rework to undo later.  Or might not, depending on how you implement it.  The 
interim approach you choose now should be informed by foresight.

Full-screen repaint approach that will require rework later:

- One function draws everything in sequence.  It gets called every frame.

Full-screen repaint approach that will be easy to integrate into a partial 
update scheme:

- A separate function exists for drawing each logical unit of the screen.
- Every frame, one function calls all the separate functions in sequence.

Or something like that.
