flags (2 bytes): A 16-bit unsigned integer that contains graphics command flags common to all PDUs. No common graphics command flags are specified; therefore, this field MUST be set to zero.

pduLength (4 bytes): A 32-bit unsigned integer that specifies the length of the graphics command PDU, in bytes. This value MUST include the length of the RDPGFX_HEADER (8 bytes).
