------- Additional Comments from Peter Kasting <pkasting at google.com>
This moves the private reader objects in several decoders from being raw
pointers to OwnPtrs, to simplify the code a little.  Since I'm touching this
part of the GIF decoder anyway, it also removes GIFImageDecoderPrivate, since
that wrapper class doesn't seem to add much value beyond simplifying the
"decode" API call, and it takes up a big chunk of space.
