start passing left/right margins everywhere

I have a set of changes that passes all tests, but I'm going to commit
them very carefully to ensure I don't miss any call-sites. In this
commit I'm adding the args to:
  - Text.draw
  - Text.tweak_screen_top_and_cursor

But calls within them don't yet pass them where they should. In this
manner I'm going to progress systematically from the top down.
