A tiny set of integers, which provides an indirection mapping from the conceptual space of an HdRprim's resources (topological, primvar & instancing) to the index within HdBufferArrayRangeContainer, where the resource is stored.
Each HdDrawItem contains a HdDrawingCoord, with the relevant compositional hierarchy being:
HdRprim | +–HdRepr(s) | | | +–HdDrawItem(s)-------—. | | | | +–HdDrawingCoord | | | (mapping provided by HdDrawingCoord) +–HdRprimSharedData | | | +–HdBARContainer <-----—+
Having this indirection provides a recipe for how to configure a drawing coordinate, which is a bundle of HdBufferArrayRanges, while they are shared or not shared across different representations constructed on the same prim.
