It would be useful to be able to cheaply convert between an Atom<StyloAtomSet>, an Atom<ServoAtomSet>, a DefaultAtom, etc. This would allow for interop between different crates without a performance penalty and without them all needing to coordinate on which set of static atoms to use.
However currently a dynamically allocated Atom is keyed by it's hash and that hash varies between static atom sets. So converting between Atom types requires reallocating.
I believe that implementing this would involve changing the Hash implementation of Atom to hash the content of the Atom rather than 64 bit value (see also #224 for why this may be a good anyway). At which point
