No list unfortunately. And since processes are pluggable, and how their
parameters are parsed are pluggable I think it would be hard to come up with
an exhaustive list. Perhaps trying to sum up all the ppio implementations.
Regarding rasters... I have never written a process that takes a raster, so
not sure what that looks like. There should be lots of examples though.
There is no support (yet) in geoscript for rasters so it would be just the
straight java class, grid coverage, or grid coverage reader, etc... that
would be the parameter type. If I understand correctly.
