Interference in depth map (vertical lines)

[GoogleCodeExporter]

The depth map appears to have vertical lines running through it which get 
closer together the longer the sketch runs. Initially there are just two or 
three, but they seem to creep closer together over time so that there are more 
of them.

These were visible on the SimpleOpenNI_User sample sketch.

I am using version 0.11 with OSX 10.6 on a MacBook Pro.

See attached screenshot.

Seams to be the ways the camera works. Also keep in mind, the depth value is 
transformed into a 8Bit(for r,g,b)from a 16bit value, so you lose accuracy. 
Normally you use anyways the depthMap with the 16bit value, not the 
dephtMapImage bitmap.
