16-bit depth data with distance values at each pixel


Description
===========

This is a 16-bit format, representing depth data. Each pixel is a
distance to the respective point in the image coordinates. Distance unit
can vary and has to be negotiated with the device separately. Each pixel
is stored in a 16-bit word in the little endian byte order.

**Byte Order.**
Each cell is one byte.
