get the clone timer maybe to ask if the user wants to use symbolize
to make this work with PeopleRatioPlay, gonna have to make asymbol for each color, and replace the clone symbol with the cloneSymbol for the right color
in the backend, an SVGDef will have to specify if it wants to use symbolize based clone by default.
in the frontend, we have to respond to the desired to render with Symbolize (either from backend specification, or because cloneTimer offers it as an option and the users chooses it)
