No, you would have to assume that the plugin does something pretty 
close to what you actually *tell* it - which may be a linear ramp, or 
whatever the API supports.

So, if the API supports linear ramps, plugins should *do* linear 
ramping when you tell them to. Obviously, approximations inside 
plugins will be somewhat risky, but I can't see any sane way of 
avoiding that entirely.
