Like I wrote elsewhere, I seem to be sure that a white paper by Rick Brewster about multithreading used in Paint.NET once existed. I am not able to find any reference to this white paper again however. Does it (still) exist? And if so, where?
EDIT: Found out in comments to an unrelated question that Paint.NET is still free, but code is no longer available? Is this related to the fact that I can't seem to find that white paper any more?
EDIT2: Went straight to the horses mouth on this and will return any answer that I get here. In the meantime any answer you guys might have is more than welcome!
