Bug 158941 – When navigating, discard decoded image data that is only live due to page cache.

• Component: Images
• Status: REOPENED

[Andreas Kling]

We could hasten the dropping of decoded image data when a CachedImage is really only used by page cached pages.

Committed r202231: <http://trac.webkit.org/changeset/202231>

All reviewed patches have been landed.  Closing bug.

[Chris Dumez]

Note that it seems that the Mac PLT regressed around the time this patch landed. I am working on confirming the regression came from this change.

[Chris Dumez]

Reverted r202231 for reason:

Seems to have regressed PLT on both iOS and Mac (very obvious on iOS Warm PLT)

Clear 1% progression on MacBookPro PLT from the roll out.
