SVN commit 646166 by cgilles:
digiKam from trunk : CImg::Greycstoration interface : bugfix : if an image with alpha \
channel is processed by CImg, handle this channel properlly. The old implementation \
lost alpha channel. Nota : this problem still exist with the old CImg interface of \
DigiKamImagePlugins. This patch can be easily backported to 0.9.1 \
package.
