Because decode in 8 bits color depth or in 16 bits color depth a RAW files
is not the same

gqview do not support 16 bits color depth and i suspect than it use an half
decoding version of RAW file to speed up loading. This is fine for viewing,
and only viewing, but not to edit.

digiKam use also this wait to display faster RAW picture on Light Table.
