Bug: 78866720 The client in Android calls newPictureSnapshot, which results in copying the mutable SkBitmap into a newly allocated one in each frame. Avoid this by calling SkMakeImageFromRasterBitmap with kNever_SkCopyPixelsMode. Make SkAnimatedImage copy on write, by copying before decoding if the bitmap's pixel ref is not unique. Android's AnimatedImageDrawable's current architecture only decodes one frame in advance, so it will never need to perform the copy on write. This will save one bitmap allocation per GIF frame. Add a test to verify that copy on write works as expected.
