Ah, I get it now. I'm not sure about it either - a user might want to
connect the gain reduction to another plugin's input for whatever
reason, or conversely, connect a 'data' port to a viewer - e.g. an audio
out to an FFT scope. If the hint doesn't prevent this, I have no
argument against having it.

Yeah. That's just my stream-of-consciousness rambling coming in :)
s/"A control with this hint"/"Randomising a control"/

The word 'initialisation' appears in the comment at the top of the
current header, so UK I suppose...
