\begin{Details}\relax
\code{banking} is a crude banking function used when aspect="xy" in
high level Trellis functions. Its usually not very menaingful except
for \code{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.
