Use partial style application for non-cacheable presentational hint style
https://bugs.webkit.org/show_bug.cgi?id=274081
rdar://127995820
Reviewed by Alan Baradlay.
Presentational hint style especially in SVG often uses many unique property
values that
miss the the matched declarations cache. We can still use the cache partilly
for such cases
by applying the presentational properties on top of the existing cache entry.
* Source/WebCore/style/ElementRuleCollector.cpp:
(WebCore::Style::ElementRuleCollector::addElementStyleProperties):
(WebCore::Style::ElementRuleCollector::matchAllRules):
Enable partial caching for SVG presentational hints.
(WebCore::Style::ElementRuleCollector::addElementInlineStyleProperties):
This could also be applied to inlne style but this patch does not implement it.
(WebCore::Style::ElementRuleCollector::addMatchedProperties):
* Source/WebCore/style/ElementRuleCollector.h:
* Source/WebCore/style/MatchResult.h:
(WebCore::Style::operator==):
(WebCore::Style::MatchResult::cacheablePropertiesEqual const):
New equality comparison that ignores non-cacheable properties.
(WebCore::Style::add):
* Source/WebCore/style/MatchedDeclarationsCache.cpp:
(WebCore::Style::MatchedDeclarationsCache::computeHash):
(WebCore::Style::MatchedDeclarationsCache::find):
* Source/WebCore/style/PropertyCascade.cpp:
(WebCore::Style::PropertyCascade::addMatch):
* Source/WebCore/style/PropertyCascade.h:
* Source/WebCore/style/StyleResolver.cpp:
(WebCore::Style::Resolver::applyMatchedProperties):
Apply non-cacheable properties after cache hit.
