26   * never generates 0, so we can use this for unspecified normals.
27   *
28   * Vertex ID's are encoded using the bottom 8 bits of a 4-byte integer
29 < * to index a vertex in a patch indicated by the 20 bits above (9-29).
30 < * For triangle ID's, the top 10 bits (11-31) indicate the patch, and
31 < * the 10th bit indicates whether the triangle joins patches.

32   * If not, then the bottom 9 bits index into the local PTri array.
33 < * If it's a joiner, then the 9th bit indicates whether the triangle joins
33 > * If it's a joiner, then the 8th bit indicates whether the triangle joins
34   * two patches, in which case the bottom 8 bits index the PJoin2 array.
35   * Otherwise, the bottom 8 bits index the PJoin1 array.
