Detailed Description

Plugin adds a scene index that declares hdprman-specific dependencies to trigger the necessary invalidation.

It currently declares 2 dependencies: (a -> b to be read as "a depends on b")

1. Volume -> Volume Field Binding This declaration registers the volumeFieldBinding data source locator of a volume prim to be invalidated if any of the targeted volume fields changes. That is, if, e.g., the filePath of a volume field changes, then the volume using that volume field will be dirtied so that HdPrmanVolume will update which 3d textures it will use.
2. Light -> Light Filter This declaration registers the light data source locator of a light prim to be invalidated if any locator of a targeted light filter changes.
