* ccanalyze.c (analyze): use Alpha channel and selection
channel info when available to build the histogram and to
include/exclude colors in the color count. Fixes bug #121097
and handling of INDEXEDA images which was broken.
(histogram, insertcolor, fillPreview): updated to use
gdoubles where appropriate.
