- window-scroll-functions (when a window's starting pos changes)
- fontification-functions (when a piece of text needs to be displayed)
- before/after-change-functions (when a piece of text is modified)
- window-start and window-end
- pre/post-command-hook (run before/after each command, so you can detect
  cursor motion)
