This is mainly for the benefit of fellow library developers, whose library depends beginRaw() / endRaw(). I have had some success in updating my povwriter library (export to povray), to work with the current svn version of processing-2.0. For the new version of processing your raw export class should inherit from PGraphics (rather than PGraphics3D). For some reason or other I found keyboard entry to be pretty dodgy (perhaps it doesn't get polled too often), so I was prompted to create my own simple button gui, this worked rather well see my blog.
