i finally read the documentation about "webcam passthru" for virtualbox,
and now i get an image in photobooth and ... Pd. hooray.

i fixed a couple of things, namely:

- disabled the debugging output, which would dump the entire raw image
data to the terminal...

fixed. this was a traditional error with converting ABGR to ARGB.
videoAVF now uses AUV by default (but can be switched to RGBA)

that was just a leftover from porting the ofx code.
i've remove it.

i noticed this too. still needs fixing.
