Detailed Description

IRdSurfaceIdIndexStream:

• Holds per-triangle custom surface identification indices.
• These indices are primarily used by widgets to distinguish between various surfaces.
• The stream is part of IRdMesh and is stored in Triangle stream group.
• Stream is identified by STREAMID_TRIANGLES_SURFIDS id.
