Yes.

Are you sure ?

I'll test.

The comments for the function say:
" Uses alg. similar to floodfill - it adds one seed per every color in
  palette to its best position. Then areas around seed are filled by
  same color because it is best approximation for them, and then areas
  about them etc..."

I thought one could expect a floodfill algorithm to preserve the islets of
exact matching between RGB triplets and indexes.
