overridevirtual

determine the resolution of this node

Note: this method will not set the resolution, this is the responsibility of the caller

Parameters

resolution	the result of this operation
preferredResolution	the preferable resolution as no resolution could be determined

Todo:: : may not occur!, but does with blur node
