In directory sc8-pr-cvs1:/tmp/cvs-serv30066/Lib
Many changes. See Changes. Rearranged Transform and Cartography
to fit into the usual source scheme; added long-promised truncation
option to range(); modified indexND to use range(); RGB bug fixes to
Transform code; auto-scaling added to ->map() method.
Also eliminated permissive-slicing tests of indexND (range is not yet
fully permissive but will be RSN)
