------- Additional Comments from Hin-Chung Lam <hclam at google.com>
The seems big but if you focus on ImageDecodingStore and ImageFrameGenerator
the others are just test and changes to mock modules.

ImageDecodingStore

Added logic to handle incomplete cache entries.

ImageFrameGenerator

Added logic to resume decoding using a cached decoder. The change has some code
move involved to share code with decoding starting from scratch.
