Refreshing paths while navigating #69
Description
The caluclation of the shortest path should be updatable while the visualization is running.
Occuring problem is the movement of the path location samples, so that every recalculation of the path would render in a jerky refresh.
This only affects bezier viusalizers for now.
Resolution would be a setup that remembers the already rendered points and waits until all "wandering particles" have moved to the end of their paths before discarding, while new "wandering particles" start on the newly updated path.
