Resolves a 3D Tiles / terrain uri relative to its parent tileset URL, inheriting
any query parameters the parent carries that the child omits. This is how a key /
session token propagates down a tree: the parent (root) URL holds ?key=… (Google,
MapTiler) and/or the response embeds a ?session=… (Google Photorealistic), and
every descendant request inherits whatever it doesn't already specify.
