Interleaved grey-scale image, e.g. from a stereo-pair


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

This is a grey-scale image with a depth of 16 bits per pixel, but with pixels
from 2 sources interleaved and unpacked. Each pixel is stored in a 16-bit word
in the little-endian order. The first pixel is from the left source.

**Pixel unpacked representation.**
Left/Right pixels 16-bit unpacked - 16-bit for each interleaved pixel.
