Thanks for your questions. In fact, Chormium change in r92782 has already existed in almost all of the other ports, per ChangeLog of r92782

      "This causes us to call CachedImage::didDraw() which calls CachedResource::didAccessDecodedData() which updates 
        the LRU for decoded image data and potentially prunes the cache. This is already done by almost all of the other ports."

r92782 is to make Chromium behave the same as other ports, so this performance regression issue not only exists in 
Chromium but also exist in other ports (such as cairo, openvg, qt). This patch will also benefit other ports. It can be 
tested with automated regression test.
