Add SkAndroidCodec::computeSampledSize
Bug: b/63909536
Android's ImageDecoder API takes as input an arbitrary width and height
to scale the image to. Internally, this uses SkAndroidCodec to sample,
and then (if not a perfect match) scales to the desired size with
drawing.
computeSampledSize is a modified version of what ImageDecoder currently
does to convert from arbitrary dimensions to a sampleSize. Moving it
here allows it to be shared by SkAnimatedImage. The modified version
also corrects two bugs:
- a client using the dimensions returned by getSampledDimensions
previously may have resulted in ImageDecoder decoding to a larger
size and then scaling it. (example found in tests: dog.jpg is
180 x 180. getSampledDimensions(8) returns 23 x 23, but the old
method resulted in using sampleSize of 7 and downscaling the resulting
25 x 25 image.)
- recompute the sampleSize based on the size returned by
getSampledDimensions.
