please read the reqs document on the design of the parameter control
system. this is (one of) the central issue(s) here: we have already
agreed that the host mediates *all* parameter changes in order to
allow sample-accurate, graph-wide, consistent undo/redo/automation.
we even spent a week or three debating and designing an odd kludge
called an "actor" to give plugins the chance to pre-process parameter
changes, precisely so as not to violate this requirement.
