3.2.5.8.1 MILCMD_GDISPRITEBITMAP

The server SHOULD set the logical surface handle for a TYPE_GDISPRITEBITMAP by sending a MILCMD_GDISPRITEBITMAP message for the targeted resource. The server sets the logical surface handle to the hlsurface message field. This handle is used by the client to get surface data and attributes for a surface created by the client in response to messages received as part of the protocols specified in [MS-RDPEDC], [MS-RDPEGDI], and [MS-RDPBCGR].
