Ortonizer

For Processing 0109 Beta
(recompiled with 0124 while contemplating 0125 blend modes, Jan 2007)

An implementation of a technique named after photographer Michael Orton.
For example see the Orton Pool on Flickr.
An image is brightened, then blurred then blended with itself
to achieve a soft diffusion highlight, almost an airbrushed effect.
(Orton's original technique involved overlaying two separate negatives that
were overexposed by controlled amounts, one sharp focused, one soft focused.)
