[PD] processing webcam input with GEM

[Max Neupert]

That's interesting; i recently had a project (yesterday) where i tried 
to use pd, GEM and a Logitech Quickcam (Pro 4000) on a WinXP and pd 
crashed when i loaded a pd patch using GEM objects. after uninstalling 
the Logitech software pd ran nicely again - but i could not use the 
cam.
weired.
