3.3.5.3 Drawing Operations Management

After a logical surface and its associated redirection surface are created, the redirection surface is targeted by primary, secondary, and alternate secondary drawing orders, as specified in section 3.3.5.1 of [MS-RDPEGDI]. The SWITCH_SURFOBJ message is sent when a drawing order targets a different redirection surface than the previous one.

Drawing to a redirection surface can happen only after a redirection surface is created and is attached to a logical surface.
