// D3DXSHPRTCompSuperCluster:
// --------------------------
// Used with compressed results of D3DXSHPRTSimulation.
// Generates "super clusters" - groups of clusters that can be drawn in

// to group the clusters.
//
// Parameters:
// pClusterIDs
// NumVerts cluster ID's (extracted from a compressed buffer)
// pScene
// Mesh that represents composite scene passed to the simulator
// MaxNumClusters
// Maximum number of clusters allocated per super cluster
// NumClusters
// Number of clusters computed in the simulator
// pSuperClusterIDs
// Array of length NumClusters, contains index of super cluster
// that corresponding cluster was assigned to
// pNumSuperClusters
// Returns the number of super clusters allocated

// D3DXSHPRTCompSplitMeshSC:
// -------------------------
// Used with compressed results of the vertex version of the PRT simulator.
// After D3DXSHRTCompSuperCluster has been called this function can be used
// to split the mesh into a group of faces/vertices per super cluster.
// Each super cluster contains all of the faces that contain any vertex
// classified in one of its clusters. All of the vertices connected to this
// set of faces are also included with the returned array ppVertStatus
// indicating whether or not the vertex belongs to the supercluster.
//
// Parameters:
// pClusterIDs
// NumVerts cluster ID's (extracted from a compressed buffer)
// NumVertices
// Number of vertices in original mesh
// NumClusters
// Number of clusters (input parameter to compression)
// pSuperClusterIDs
// Array of size NumClusters that will contain super cluster ID's (from
// D3DXSHCompSuerCluster)
// NumSuperClusters
// Number of superclusters allocated in D3DXSHCompSuerCluster
// pInputIB
// Raw index buffer for mesh - format depends on bInputIBIs32Bit
// InputIBIs32Bit
// Indicates whether the input index buffer is 32-bit (otherwise 16-bit
// is assumed)
// NumFaces
// Number of faces in the original mesh (pInputIB is 3 times this length)
// ppIBData
// LPD3DXBUFFER holds raw index buffer that will contain the resulting split faces.
// Format determined by bIBIs32Bit. Allocated by function
// pIBDataLength
// Length of ppIBData, assigned in function
// OutputIBIs32Bit
// Indicates whether the output index buffer is to be 32-bit (otherwise
// 16-bit is assumed)
// ppFaceRemap
// LPD3DXBUFFER mapping of each face in ppIBData to original faces. Length is
// *pIBDataLength/3. Optional paramter, allocated in function
// ppVertData
// LPD3DXBUFFER contains new vertex data structure. Size of pVertDataLength
// pVertDataLength
// Number of new vertices in split mesh. Assigned in function
// pSCClusterList
// Array of length NumClusters which pSCData indexes into (Cluster* fields)
// for each SC, contains clusters sorted by super cluster
// pSCData
// Structure per super cluster - contains indices into ppIBData,
// pSCClusterList and ppVertData
