I thought I'd point out that another common sample structure, with
similar issues, is the Bayer format.  It's a popular optical filtering
technique for capturing color images using a single CCD, in digital
cameras.  It's structured as a checkerboard consisting of green and
blue/red samples.  It's typically exposed to software via RAW files
(vendor-specific files available from most digital still cameras), and
is also a format supported by the IIDC 1394-based Digital Camera
Specification (both 8 & 16 bits per sample).
