It doesn't bother me too much that saving associated-alpha tiffs is 
lossy (in the transparent areas) because this seems to be something 
that TIFF users expect.  I would like for the GraphicsMagick APIs and 
utilities to continue working similar to before.  The only question is 
if it is ok to automatically promote a colormapped image to TrueColor 
type when it is saved.
