It seems like we should store "lower-level information" in this class. If we
stored whether we have min-track min-content or max-content and the same for
max-content, we could regenerate all these booleans.

That said, it's a space vs memory trace-off so we may need good data and hold
onto that until we have aligned our algorithm with the specification to see what
we actually need.

Yeah, that's actually what I'm partially doing by defining
minTrackBreadthIsMinContent. Anyway I agree that with the 4 booleans you propose
we should be done.
Good point.
