// Because of a bug in processing.org the MULTIPLY blendMode does not take into account the alpha of
// either source or destination.  If this gets corrected, tweaks to the stroke alpha might be more 
// representative of a Copic marker.  Right now it over emphasizes the darkening when overlaps
// of the same pen occur.
