                                     8b subprecision); (16.0) fixed format.
END_TYPE              17:16  0x0     Specifies how ends of lines should be drawn.
                                     POSSIBLE VALUES:
                                     00 - Horizontal

SORT                  18     0x0     R520+: When enabled, all lines are sorted so that V0 is
                                     vertex with smallest X, or if X equal, smallest Y.
                                     POSSIBLE VALUES:
                                     00 - No sorting (default)
