performance
https://bugs.webkit.org/show_bug.cgi?id=292066
<rdar://133094903>
Reviewed by Simon Fraser.
Introduce a singleton cache to limit the amount of
`LayoutShape::createRasterShape` calls.
* Source/WebCore/page/InteractionRegion.h:
* Source/WebCore/page/InteractionRegion.cpp:
(WebCore::InteractionRegionPathCache::singleton):
(WebCore::InteractionRegionPathCache::get):
(WebCore::InteractionRegionPathCache::add):
(WebCore::InteractionRegionPathCache::clear):
(WebCore::InteractionRegion::clearCache):
Add the new Cache class, backed by a WeakHashMap.
Key the entries on the Image and its FloatSize.
(WebCore::interactionRegionForRenderedRegion):
Check the cache before calling `createRasterShape`.
* Source/WebCore/page/MemoryRelease.cpp:
(WebCore::releaseNoncriticalMemory):
Clear the InteractionRegion cache as part of the non
critical memory release.
