Arguments for WINDOWS_EXTENSIONS.register_root_extender.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

root: UiNode

The window root content, extender must wrap this node with extension nodes or return it for no-op.
