===== BISECT JOB RESULTS =====
Status: completed


===== SUSPECTED CL(s) =====
Subject : Remove duplication of encoded image data
Author  : hajimehoshi
Commit description:
  
Now there are at least two encoded image data: one is in Image/ImageResource as
SharedBuffer and the other is in DeferredImageDecoder as SkRWBuffer. This CL
removes former when possible (non-icon bitmaps), and generate the SharedBuffer
from the SkRWBuffer if needed.
