 \item Updated \code{psSpline1D} to use a vector for the \code{knots}, and specified types.
 \item \code{psHistogram.nums} changed to type F32 to accomodate errors in the values.

+\item Synchronized use of \code{mask} throughout.  A non-zero mask value means that the
+corresponding value shall not be used.  Affected: polynomials (including plane transformations),
