2.2.7.1.3 Order Capability Set (TS_ORDER_CAPABILITYSET)

The TS_ORDER_CAPABILITYSET structure advertises support for primary drawing order-related capabilities and is based on the capability set specified in [T128] section 8.2.5 (for more information about primary drawing orders, see [MS-RDPEGDI] section 2.2.2.2.1.1). This capability is sent by both client and server.

If an order is supported, the byte at the given index MUST contain the value 0x01. Any order not supported by the client causes the server to spend more time and bandwidth using workarounds, such as other primary orders or simply sending screen bitmap data in a Bitmap Update (sections 2.2.9.1.1.3.1.2 and 2.2.9.1.2.1.2). If no primary drawing orders are supported, this array MUST be initialized to all zeros.
