Add SPI for telling WebKit to prefer pictograph glyphs over monochrome ones https://bugs.webkit.org/show_bug.cgi?id=122608 Reviewed by Dan Bernstein. Based on patches by Dan Bernstein. Source/WebCore: Test: fonts/font-fallback-prefers-pictographs.html Created a mechanism to append a font to the end of a font's fallback list, before the system fallback list. This mechanism is used when Settings::fontFallbackPrefersPictographs() is true to insert a pictograph font ahead of a monochrome one from the system fallback list. * WebCore.exp.in: Moved __ZN7WebCore8Settings33setFontFallbackPrefersPictographsEb outside of an iOS platform guard. * css/CSSFontSelector.cpp: (WebCore::CSSFontSelector::fallbackFontDataCount): Retuned 1 if pictograph fonts are preferred. (WebCore::CSSFontSelector::getFallbackFontData): Returned the pictograph font's FontData if it is preferred. * css/CSSFontSelector.h: * page/Settings.cpp: (WebCore::Settings::Settings): Initialized m_fontFallbackPrefersPictographs to false. (WebCore::Settings::setFontFallbackPrefersPictographs): Set m_fontFallbackPrefersPictographs and called Page::setNeedsRecalcStyleInAllFrames(). * page/Settings.h: (WebCore::Settings::fontFallbackPrefersPictographs): * platform/graphics/FontGlyphs.cpp: (WebCore::FontGlyphs::realizeFontDataAt): Realized the selector's fallback font if necessary. * platform/graphics/FontSelector.h: * style/StyleResolveTree.cpp: (WebCore::Style::resolveTree): Removed iOS platform guards. * testing/InternalSettings.cpp: (WebCore::InternalSettings::setFontFallbackPrefersPictographs): Set the corresponding WebCore::Setting. * testing/InternalSettings.h: Defined an internal setting for the test. * testing/InternalSettings.idl: Ditto. Source/WebKit/mac: * WebView/WebView.mm: (-[WebView _setFontFallbackPrefersPictographs:]): Called WebCore::Settings::setFontFallbackPrefersPictographs(). * WebView/WebViewPrivate.h: LayoutTests: * fonts/font-fallback-prefers-pictographs-expected.html: Added. * fonts/font-fallback-prefers-pictographs.html: Added.
