@param[in] name The string the plugin was registered with.

catalog fields. Output fields should be added to the
output schema. While most plugins will not need to map
fields from the reference schema, if they do so, those fields
will be transferred before any plugins are run.

WCS-transformed position of the reference object, so plugins that only
require a reference position should not have to access the reference object
