+// I've made some changes to the Scenery handling. Basically just tidy ups.
+// The main difference is in tile.[ch]xx where I've changed list<fgFRAGMENT> to
+// vector<fgFRAGMENT>. Studying our usage patterns this seems reasonable.
+// Lists are good if you need to insert/delete elements randomly but we
+// don't do that. All access seems to be sequential. Two additional
+// benefits are smaller memory usage - each list element requires pointers
+// to the next and previous elements, and faster access - vector iterators
+// are smaller and faster than list iterators. This should also help
+// Charlie Hotchkiss' problem when compiling with Borland and STLport.
