[PD] usage of gems

[cgc at humboldtblvd.com]

i take it you are using osx?  pix_write will write each frame to disk as a
photo-jpeg file. i suggest making a folder to write the files into as pd/bin is
the default.  you can make the files into a qt .mov by opening the first file in
the series in qtplayer.app and then saving it as a .mov (this might require
qtpro).  one caveat for pix_write exists right now: the recorded images will be
upside down!  i decided not to add a function to flip the image before writing
because it slowed down the process too much.  the reason the image is flipped
has to do with OpenGL and Quicktime disagreeing about the image origin.  GL
starts drawing in the bottom left, QT/QD starts on the top left.  i have
mentioned this to Apple, but they have not issued a work-around yet.
