If the TS_STANDARD (0x01) flag is set, the order is a primary drawing order. If both the TS_STANDARD (0x01) and TS_SECONDARY (0x02) flags are set, the order is a secondary drawing order. Finally, if only the TS_SECONDARY (0x02) flag is set, the order is an alternate secondary drawing order.
-
More flags MAY be present, depending on the drawing order class. The flags listed are common to all three classes of drawing orders.
