+ <summary>

+ The esitimated memory size which would be reduced when reusing disk cache is

+ implemented. If it is 100% sure that the encoded data is in disk cache, the

+ same data in memory can be dropped to reduce memory usage. This is

+ rencorded when an ImageResource is pruned. See crbug/664437.
