Cog colormap bug

 
I made a reproducable failure for the colormap issue in cog.

get the image at http://cobalt.cs.duke.edu/pub/CogColorMapBug.zip
then do:

(CIconLibrary default at: #SubMenu) colormapIfNeededForDepth: 32

On cog 2348 and 2349 on linux, it fails the first two times
you execute it, then succeeds afterward
