 \item Added \code{psPlaneAlloc, psSphereAlloc, psProjectionAlloc}.

+\item \code{psList}:
+  \begin{itemize}
+  \item Adopted new names: \code{psListGetAndIncrement,
+    psListGetAndDecrement} instead of \code{psListGetNext,
+    psListGetPrev} --- clearer description of functionality.
+  \item Changed \code{PS_LIST_HEAD = 0} and \code{PS_LIST_TAIL = -1};
+    negative indices specify an item relative to the end of the list.
+  \item The action of retrieving data from a list (with one of the
+    three \code{psListGet} functions) is considered ``borrowing'' the
+    reference, so no action is performed on the reference counter.
+    Removed other mentions of reference counters, since these were not
+    necessary.
+  \item \code{mutable} boolean in \code{psListIterator} specifies
+    whether \code{psListAddAfter} or \code{psListAddBefore} may be
+    used to modify the list through the iterator.  This allows the use
+    of \code{const psList} in \code{psListIteratorAlloc}.
