https://bugs.webkit.org/show_bug.cgi?id=65904 Reviewed by Kenneth Russell. Source/WebCore: Use Uniscribe's OpenType APIs to shape complex text to support -webkit-font-feature-settings property. No new tests. css3/font-feature-settings-rendering.html should pass by this patch. * platform/graphics/chromium/UniscribeHelper.cpp: (WebCore::loadOpenTypeFunctions): (WebCore::UniscribeHelper::UniscribeHelper): Calls loadOpenTypeFunctions if needed. (WebCore::UniscribeHelper::fillRuns): Uses ScriptItemizeOpenType() if possible. (WebCore::UniscribeHelper::shape): Uses ScriptShapeOpenType() if possible. (WebCore::UniscribeHelper::fillShapes): Adds OpenType script tag as an argument. (WebCore::convertFeatureTag): Added. (WebCore::UniscribeHelper::setRangeProperties): Added. * platform/graphics/chromium/UniscribeHelper.h: * platform/graphics/chromium/UniscribeHelperTextRun.cpp: (WebCore::UniscribeHelperTextRun::UniscribeHelperTextRun): Calls setRangeProperties(). LayoutTests: Adds expectations of css3/font-feature-settings-rendering.html for Chromium win port. Since Uniscirbe OpenType APIs are not available on WinXP by default, the test could fail on WinXP. * platform/chromium-win/css3/font-feature-settings-rendering-expected.png: Added. * platform/chromium-win/css3/font-feature-settings-rendering-expected.txt: Added. * platform/chromium/test_expectations.txt: VISTA and WIN7 should pass css3/font-feature-settings-rendering.html. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@96582 268f45cc-cd09-0410-ab3c-d52691b4dbfc
