32 * The VRDP server gets an information about a graphical update as a pointer
33 * to a memory block and the size of the memory block.
34 * The memory block layout is:
35 * VRDPORDERHDR - Describes the affected rectangle.
36 * Then VRDP orders follow:
37 * VRDPORDERCODE
38 * A VRDPORDER* structure.
39 *
40 * If size of the memory block is equal to the VRDPORDERHDR, then a bitmap
41 * update is assumed.
