- FilteringExtension now emits the filtering state changed event when reseting the filtering state - BasitPass no longer applies the per vertex color indices each frame - ViewModes extension now listens for filtering state changes and have any active BasitPass reset it's color indices on a filtering reset event. Not great, not terrible but it avoids us having to double cache the per vertex color indices.
