haku should have the possibility to work with bitmap images and paint them onto the wall. For starters, I think we should have the following functions:

capture
  r : rectangle
  -> image

paint
  i : image
  destination : rectangle
  -> scribble

paint
  i : image
  destination : rectangle
  source : rectangle
  -> scribble

capture takes a picture of the wall. You give it a rectangle to capture, it returns an image containing the contents of that rectangle.
paint paints and image onto the wall. You can select a source rectangle on the image if you'd like.

Things I'm not so sure about:

What about scale factors? wrapping behaviours?
Is haku going to have enough memory to store image bitmaps?
