Plugins must gracefully handle out-of-range values, typically either by
clamping or ignoring. The ranges in LV2 are "soft".

There could be an extension for "hard" limits, as a micro-optimization,
but I don't know if one exists (or if the performance advantage of
avoiding an if or two is worth the hassle).
