In the initial patch, we modified the subset passed to incremental decoding to account for sampling in Y. This allowed SkSampledCodec to use a tighter bounds. But it also means that the implementation cannot distinguish between lines that are excluded due to subsetting and those excluded at the beginning and end due to sampling. This becomes problematic in GIF (crrev.com/2045293002), which may need to fill, requiring it to reconstruct the actual destination. In truth, SkGifCodec does not need to support subsets, but cannot distinguish between the tighter bounds and a true subset. Fix this by passing the scaled subset to incremental decode, without using the tighter bounds. Make SkSampler::rowNeeded take the starting coordinate into account. In SkPngCodec, compute the number of rows needed in the output, and use that as a signal to stop.
