That could work, too. I want to be careful how much we expect the plugin
coder to do, though.

my version has had ints from the start.

Is there a justification? 32 bit CPUs are bad at 64 bit math. Maybe a hint
that says INT64, otherwise assume int32 ? Do we assume signed or unsigned?
having it be 64 bits means we need to deal with sign extension.

They can be, it's just not so accurate. If you want to swing between 0 and
1000 in one block, set a ramp event.
