+ * affect a particular CompositorBridgeParent and all the content that it
+ * renders.
+ *
+ * This class is intended to be created by a platform widget (but NOT
+ * PuppetWidget) and passed to the graphics code during initialization of the
+ * top level compositor associated with that widget. The options are immutable
+ * after creation. The CompositorBridgeParent holds the canonical version of
+ * the options, but they may be accessed by other parts of the code as needed,
+ * and are accessible to content processes over PCompositorBridge as well.
