  <!-- This icon has two entries, a 16-color one (first) and a 256-color one
       (second).  The 256-color entry has both its bit count and its color count
       set to 0 in the directory; the decoder should consider the 0 color count
       to mean 256 and prefer this entry over the 16-color one, rather than
       treating it as 0 and decoding the 16-color entry. -->
