[PD] Motion Tracking etc

[Jonathan Goodwin]

Ok, thanks for all the tips so far, all seems to be going to plan.

I'm having a problem figuring out the resolutions of my video components and
the gem_win size, something which is apparently important to make chroma_key
work well.

When I create a new GEM Window,  PD reports it's created a 500x500 window.
But even if I set the pix_snap2tex dimensions to match, the screen grab from
my i-sight comes out at different proportions. I've got both a pix_snap2tex
feed and an unaffected pix_video feed rendering to the same 4 3 rectangle,
but the only the pix_snap2tex is appearing wrongly.
