Is XnShiftToDepthConvert() still done in software?

[Rafael]

As per information in this thread:
https://groups.google.com/group/openni-dev/browse_thread/thread/478f9167acc30759/bc6f9c1cb751b72d

the method XnShiftToDepthConvert() is called in each frame. However,
when I profile I don't see it appear anywhere in the report. It
appears as if the data read from the USB is depth in an 11-Bit format
which is then unpacked to a 16 bits per pixel format, and that's all.
But no XnShiftToDepthConvert(). Is this method still in use?

Thanks,
Rafael
