Cache RemoteController artwork bitmap size, use it in registration

Allow an app to set the artwork configuration at any point
  regardless of the registration state, and cache the width/height
  values.
If the RemoteController is already registered, apply them.
If the RemoteController is not registered, use the cached value
  when the object gets registered.
