+ * Primary class for storing recorded canvas commands, as well as per-View/ViewGroup display properties.
+ *
+ * Recording of canvas commands is somewhat similar to SkPicture, except the canvas-recording
+ * functionality is split between DisplayListRenderer (which manages the recording), DisplayListData
+ * (which holds the actual data), and DisplayList (which holds properties and performs playback onto
+ * a renderer).
+ *
+ * Note that DisplayListData is swapped out from beneath an individual DisplayList when a view's
+ * recorded stream of canvas operations is refreshed. The DisplayList (and its properties) stay
+ * attached.
