[chromium] Lazy image decoding without cache

Summary [chromium] Lazy image decoding without cache
Hin-Chung Lam
Reported 2012-11-12 17:40:07 PST
The goal is to make ImageDecodingStore be a simple image cache and does nothing more. This is the second step to refactor ImageDecodingStore and ImageFrameGenerator. The change involves moving the code to actually decode and scale an image, the code will be moved from ImageDecodingStore to ImageFrameGenerator. There should be no new code in this change.

This is the second part of refactoring, i.e. to move image decoding from ImageDecodingStore into ImageFrameGenerator. There's no new logic implemented in this change. Pending on 102019 to review / land.

This change is to make image decoding completely lazy without any caching. Next change I'm preparing is to make this lazy decoding thread-safe such that nduca@ can proceed impl-side painting and decoding.
