Fixes monochrome image preview (add some sane colors). Real 2-color palette is still used on loading the picture.
Note: can display broken preview if an image is using multiple entries with the same color, and some of them are selected for cm_clair and cm_fonce. git-svn-id: svn://pulkomandy.tk/GrafX2/trunk@607 416bcca6-2ee7-4201-b75f-2eb2f807beb1
