IconMerge
~~~~~~~~~

This command is used for merging two pictures together to form an Icon with
an alternate image.  These such icons are obviously the most popular, rather
than standard backfill, etc.

Usage is straightforward, just type IconMerge and it will lead you through,
asking for the first image (unselected), second image (selected), and the
final icon image.  In all cases .info is added for you, so don't go to the
trouble.
