Detailed Description

XXX The declarations below se can be moved to the cpp.

Plugin that chains a scene index for each of the following ops:

Resolve connections: Expand "virtual struct" connections, including evaluation of conditional actions.
Node translation: Transform materials with a UsdPreviewSurface node or MaterialX node into Prman equivalents. XXX For MaterialX nodes, current support is limited to those connected to the 'surface' terminal.
Node identifier resolution: Find shaders without nodeID's and attempt to resolve their identifier via UsdShade sourceAsset or sourceCode properties.

This plugin is registered with the scene index plugin registry for each of the Prman variants.

Subclasses implement this to instantiate one or more scene indicies which take the provided scene as input.

The return value should be the final scene created – or the inputScene itself if nothing is created.

Reimplemented from HdSceneIndexPlugin.
