> > 
> > As the CodecTest.cpp comment says, the GIF spec explicitly says that the
> > LZW literal width should be at least 2, but in practice, GIF encoders

> > GIF decoders in being more liberal in what it accepts.

> > Codec_InvalidAnimated therefore no longer has a separate "#ifdef
> > SK_HAS_WUFFS_LIBRARY" section. The first frame of the test's GIF image
> > data, being the required frame of the third frame, no longer has an
> > invalid LZW literal width according to Wuffs.
