     'banking' is a crude banking function used when 'aspect="xy"' in
     high level Trellis functions. Its usually not very menaingful
     except for 'xyplot'. It just orders the absolute slopes and
     returns a value which when adjusted by the panel scale limits will
     make the median of the above absolute slopes a 45 degree line.
