sheaf 1e4bb4bddc implement a basic brush store 
* each stroke stores the brushes it uses by reference,
    so that one can interactively edit brushes
    and see the strokes be updated in real-time
  * when writing to a file, we retrive the brush code
    from the reference, and include that information statically
