The issue is that a sender of events needs to know whether the receiver can
properly handle ramps.

Acceptable to me. We still have to either mandate that float controls
support ramps, or we have to provide the info to senders, and all senders
have to handle it properly.

yuck. Better to have generic control type converters.
