header (8 bytes): An RDPGFX_HEADER (section 2.2.1.5) structure. The cmdId field MUST be set to RDPGFX_CMDID_MAPSURFACETOWINDOW (0x0015), while the flags field MUST be set to zero.
surfaceId (2 bytes): A 16-bit unsigned integer that specifies the ID of the surface to be associated with the surface-to-window mapping.
windowId (8 bytes): A 64-bit unsigned integer that specifies the ID of the RAIL window to be associated with the surface-to-window mapping. RAIL windows are created via the New or Existing Window Order ([MS-RDPERP] section 2.2.1.3.1.2.1). The WindowId field of the Common Header ([MS-RDPERP] section 2.2.1.3.1.1), embedded within the order, contains the window ID.
mappedWidth (4 bytes): A 32-bit unsigned integer that specifies the width of the rectangular region on the surface to which the window is mapped.
mappedHeight (4 bytes): A 32-bit unsigned integer that specifies the height of the rectangular region on the surface to which the window is mapped.
