rename ParameterChanged signal in Plugin to ParameterChangedExternally to reflect its intent, and clean up the result.
The signal exists to notify listeners that something outside of the host's control (e.g. a plugin's own GUI for AU or VST)
has modified a plugin parameter. Previous code had strange feedback loops and ambiguous semantics.
Significant modification of LV2 GUI updating was required.
Still to be tested for feedback loop issues: AudioUnits
