update: Added one additional material function, double checked (after pack got declined) every shader model from ES_2 up to latest, all but one material work on all shading models.
that one specific material does not work when erosion is active, so added a warning comment, and any example particle that is not shown in ES_2 now has an alternative version working on mobile.
resubmitting now.
Edit: also updated first post to reflect the latest version of the package!
