Hi Jacopo,

Thank you for the patch.

I'm not opposed to this (despite my review of patch 5/8), but I think the _LE 
suffix isn't the right name for the new formats. _BE and _LE relate to byte 
swapping, while here you really need to describe full mirroring. Maybe a 
_MIRROR variant would be more appropriate ?
