Multiple WatchFaceService instances and hence Renderers can exist concurrently (e.g. a headless instance and an interactive instance) and using SharedAssets allows memory to be saved by sharing immutable data (e.g. Bitmaps and shaders) between them.
Note SharedAssets will be constructed on a background thread, but (typically) used and released on the ui thread.
Notification that any resources owned by SharedAssets should be released, called when no renderer instances are left.
