Among other things, this means that automation controls/lists have the actual min/max/normal/toggled of parameters, and not those inferred from the Parameter ID, which is not correct for things like plugin parameters. Pushing things down to the Evoral::ParmeterDescriptor may be useful in the future to have lists do smarter things based on parameter range, but currently I have just pushed down the above-mentioned currently used attributes.
