^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) This is a grey-scale image with a depth of 12 bits per pixel, but with
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) pixels from 2 sources interleaved and bit-packed. Each pixel is stored
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) in a 24-bit word in the little-endian order. On a little-endian machine
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) these pixels can be deinterlaced using

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) pixels cross the byte boundary and have a ratio of 3 bytes for each
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) interleaved pixel.
