Ok, I understand this is more a large thumbnail for raw images.
Nevertheless, if the color sidebar tab is opened, the histogram widget will
load the real image, the same for non-raw image formats as far as I see.
if we have a version of the image in the cache, we can take it (scale, convert
to QImage if necessary)
if we load the full image anyway (non-raw images), we can load it as DImg and
put it in the cache.
In the end, of course, we can all leave it as it is, use a kioslave, and think
about it later in 0.9. That's fine with me.
