The rectangle packers now throw a proper exception when there is no more space available; Moved interface implementations of the TransformingReadOnlyCollection into a separate file to keep the main body of the class readable

/// their parent prior to disposing them, add a Reparent(null); call before the
/// line with InternalDispose(true); in your custom Dispose() method.
/// Do not call this method during a GC run (eg. from your destructor) as it
