All the pages about Picture to People internals, like the page about Maccala features for example (http://www.picturetopeople.org/dev/maccala_features.html
), aim to show how the project is based on powerful and high quality software. A sponsor interested on using the libraries as a remote graphic design service, for example, could like to know a little about how things are inside.
I could not see your images (maybe a bug on Google groups), but I know about moiré patterns. Thanks for your suggestion.
