Oops, adding the "const" here was causing the isSizeAvailable() call to use the
const implementation instead of using the overloaded non const version in
JPEGImageDecoder, so it was always false.

Ack.

 {
     // canDecodeToYUV() has to be called AFTER isSizeAvailable(),
     // otherwise the output color space may not be set in the decoder.
