More uses:
* Vibrato/Tremolo (sounds better with continuous control)
* Fast transients (percussion synthesis)
* Smoother response to erratic input (smoothing the output from a gui
widget makes for a nicer 'feel')
In short, I support the addition of this hint to LADSPA :)

There's a syntactic ambiguity in the name AUDIO_RATE_CONTROL. Steve
uses it to describe a Controller which runs at Audio Rate (i.e. sample
clock speed). But, Janne understood it to mean a Controller *of* the
Audio Rate, which is not allowed. Maybe a different name
(CONTINUOUS_CONTROLLER?) would be clearer.
Seconded. I think including 'AUDIO' in the hint would confuse matters. A short
comment in ladspa.h could specifiy that 'continuous' means 'at audio
rate'.
