[PD] processing webcam input with GEM

[Ian Smith-Heisters]

I recently did a project in WinXP with a webcam, PD, and GEM and it 
worked beutifully. I was able to have 9 concurrently running captures 
and 3D without a decent framerate. I think there are some GEM picture 
analysis objects, but I'm not familiar with them. PDP+PiDiP on Linux is 
the best way to do this, but WinXP and GEM, perhaps with an OSC 
connection to something like Eyesweb will work. I used a Logitech Quickcam.
