Ideas + Optimization Possibilities

[McCallisterRomer]

• Allow sharing MaterialInstances across MeshRenderers
  • This has a long list of asset, serialization, and editor concerns. Really can't even think about doing it until NcGraphics (1) is gone.
• When recreating the MaterialProperties buffer (or other non-statically sized structured buffers), we could add a growth factor. (If we're individually creating an instance each frame or something, we'd continually recreate).
  • This may not be necessary, depending on what sharing instances looks like. We may be able to create the buffer once at the max size.
• When updating the MaterialProperties buffer, we update (potentially) multiple subranges to minimize transitions. Instead, we could calculate one minimum range (that includes all dirty items, and potentially non-dirty items) and just copy that single slice.
• Look into using UpdateBuffer for the vertex + index buffers.
