I'm hoping we don't need to change interfaces more than once (in which case we
have version 1 and 2). What else is the backend supposed to do besides render
an ohr-rendered image to the screen? Besides, with each revision aligned with a
release, I don't think it'll matter in 32+ years.

For the next complete release (not a "Ypsiliform + tourniquet" in the event of
an emergency bug fix), version 2 should be the accepted interface, not version
1.
You're right, though. There's no need to support both old and new interfaces in
the same backend. Perhaps the backend test should just test for 1, not a
bitwise OR with 1 after all.
Then we can allow the integer to register 4billion interface revisions, lol.
