P3D Re: Anaglyph creation

[Frederick Greenspan <greenspan@xxxxxxxxxxxxx>]

Thanks to Dan Shelley for his excellent instructions! We didn't get it
at first, trying to follow his details after we already converted our
images to b&w. Once we tried WITHOUT going to b&w, we got our first
anaglyph - and it was in color! I still don't understand how we could
succeed at this when most of the anaglyphs on the net are B&W (maybe to
make the files small enought to load in reasonable time). Anyway, thank
you!
