SceneNodeHost class Widgets

Mounts an app-owned Node subtree inside a declarative tree.

The inverse bridge to SceneSubtree: the declarative tree decides where node hangs (wrap in a SceneNode to position it), while the application owns everything inside it, imported models, procedurally generated content, nodes shared with other systems. The widget attaches node on mount and detaches it on removal; it never modifies or disposes the node's contents.

The node must not be attached anywhere else while hosted.
