Detailed Description

A data source representing a primvar. A primvar contains data, interpolation, and role, but data can be a flat value or a value/index pair. We also take location information for variability tracking.

Note: the schema for this specifies that you can return "primvarValue" for a flattened value, or "indexedPrimvarValue" and "indices" for an un-flattened value. Since we don't want to duplicate the flattening logic, we check whether indices are present and then return only one of "primvarValue" or "indexedPrimvarValue" from the result of valueQuery.
