I once asked Jonathan Sachs, creator of PWP (and also co-founder of
Lotus Corp and author of the original Lotus 1-2-3) about some people's
claims that it was necessary to do a stair step approach when uprezzing
images. His only comment was that people who believed that were not
using PWP and were obviously using poorly implemented algorithms in
other applications. :-)
