Selects the tiles to render for camera, descending while a tile's SSE
exceeds maxScreenSpaceError and it has children. REPLACE renders a tile
only when it is not refined further (leaf or good enough); ADD renders the
tile and still descends. When camera carries view + projection matrices,
tiles whose bounding volume falls entirely outside the camera frustum (and
their subtrees) are culled.
