Bugs / design issues:
- Fix cursor cropping in render function where missing
- Deal with hRelease/vRelease differently, e.g. by using Maybe to
contain width and height in the context, and behave differently if
they're Nothing (same for boxes?)
- Do we need CropLeftBy and CropTopBy if we just Translate negatively?
- Simplify attribute management (too many combinators)

Features:
- Text manipulation API
  - monoid instance
  - RLE attribute assignment with successive transformations?
  - wrapping
- Think of better library name
- Deal with multi-column characters everywhere
- Port widgets from vty-ui
- Overlays relative to a specific widget (e.g. drop-downs) using layers
but without having to know the position of the controlling widget

Performance:
- Use a zipper for the list widget, use vectors for storage, or
  generalize interface to some traversable so the caller decides what
  structure to use (e.g. tree)
- Use Vector instead of List where sensible
- Consider viewport alternative combinator that takes a hash of the data
  to be rendered, caches the hash when it renders, and only re-renders
  when it gets a new hash (and the hash goes in the viewport state that
  gets stored in the RenderState)
