I think that the combination of reference counting and explicit cleanup is a
good one, relatively easy to program correctly with, and I would lean toward
that combination.
The main cost of successfully implementing that design is making sure that each
function on DrawingBuffer is either harmless to call after clear() or contains
an assertion that it is not called after clear() with some solid reason to know
it won’t be called.
