[Paraview-developers] Forwarding optional input port to subproxy

[David Lonie]

Thanks for the tip.

AIUI, though, the Hints/ProxyList/Link method only works for
ProxyProperties, not SubProxies? (I could be completely wrong).

I'll still need someway to add an arbitrary input to the ProxyListDomain,
too.
