13===========
14
15This is a grey-scale image with a depth of 12 bits per pixel, but with
16pixels from 2 sources interleaved and bit-packed. Each pixel is stored
17in a 24-bit word in the little-endian order. On a little-endian machine
18these pixels can be deinterlaced using

27pixels cross the byte boundary and have a ratio of 3 bytes for each
