In this direction, I think you need to look the PP_Resource params up in the
resource tracker and send the host_resource. There should be lots of examples.
The idea is that the local, plugin-side resource ID is distinct from the ID the
host uses for this resource, so when you go to the host side, you need to
translate to the ID the host understands.

(same for other resources below)
