 // ViewportAnchor provides a way to anchor a viewport origin to a DOM node.
 // In particular, the user supplies the current viewport (in CSS coordinates)
 // and an anchor point (in view coordinates, e.g., (0, 0) == viewport origin,
 // (0.5, 0) == viewport top center). The anchor point tracks the underlying DOM
 // node; as the node moves or the view is resized, the viewport anchor maintains
 // its orientation relative to the node, and the viewport origin maintains its
 // orientation relative to the anchor.
