+
+ Hidden page DOM timer throttling is disabled by default in WebKit1 and
+ in WebKit2 for platforms other than Mac. Override the preference to

+ No new tests. Only adding settings to enable/disable existing features
+ and hence existing tests suffice.

+ * WebCore.exp.in:
+ * page/Page.cpp:
+ (WebCore::Page::setVisibilityState): Check if DOM timer throttling
+ and CSS animation suspension are enabled before turning them on.
+ (WebCore::Page::hiddenPageDOMTimerThrottlingStateChanged): Start or stop
+ DOM timer throttling based on page visibility and the new setting state.
+ (WebCore::Page::hiddenPageCSSAnimationSuspensionStateChanged): Ditto
+ for CSS animation suspension.
+ * page/Page.h:
+ * page/Settings.cpp:
+ (WebCore::Settings::Settings): Initialize the flags for enabling hidden
+ page DOM timer throttling and CSS animation suspension to false.
+ (WebCore::Settings::setHiddenPageDOMTimerThrottlingEnabled): Update flag
+ and notify page that the state of the setting has changed.
