[PD] pix_freenect update

hi everybody!

i did a update to my pix_freenect external for kinect and moved it into a git repo. get it here: http://github.com/kronihias/pix_freenect

ready to use binaries for osx (including libusb&libfreenect) are in the build folder.

major improvements:

• open specific Kinect sensor by serial number, not only by id (that

may change every time pd is restarted) -- useful for multiple Kinect installations

• output registered depthmap -> rgb and depth images are aligned (less

offset between those two pictures - depending on distance)

• output depthmap directly as millimeter values (16 bit in red & green

channels)

• resolution of rgb image can be set to 1280×1024

i also added a folder with examples - currently just one but i hope there will come more soon....

have fun.
