Maybe it's just me but I find extending GIL to support something like the v210 Quicktime format quite challenging (I don't want to imply that this is GIL's fault). This is a 10-bit YUV 4:2:2 format which stores 6 pixels in 16 bytes. This is an excellent example for a very complicated image format.
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).
