Takes a PID-descriptor, a type-0x6 buffer for the output [[#NativeWindow]], a [[#DisplayName]](which was previously used with [[#OpenDisplay]]), an u64 ExternalLayerId, and an u64 [[AM_services|AppletResourceUserId]]. Returns an output u64 NativeWindow_Size.

Official user-processes use an ExternalLayerId stored in a global state field if non-zero, otherwise:

Official user-processes use a LayerId stored in a global state field("...ExternalLayerId") if non-zero, otherwise:

* When AppletResourceUserId==0, [[#CreateStrayLayer]] is used instead of the OpenLayer cmd.

* When AppletResourceUserId==0, [[#CreateStrayLayer]] is used instead of the OpenLayer cmd.

* When AppletResourceUserId!=0, {unknown cmd} is used and the output from that is used for ExternalLayerId with the OpenLayer cmd.

* When AppletResourceUserId!=0, {unknown cmd} is used and the output from that is used for LayerId with the OpenLayer cmd.
