+
+        Merge r182516.
+
+    2015-04-07  Simon Fraser  &lt;simon.fraser@apple.com&gt;
+
+            Add experimental code to use custom font dilation when rendering into non-opaque contexts
+            https://bugs.webkit.org/show_bug.cgi?id=143508
+
+            Reviewed by Sam Weinig.
+
+            Add GraphicsContext::setAntialiasedFontDilationEnabled(), and set it to true
+            when rendering into a compositing layer which is not opaque (at the same location
+            where we disable font smoothing).
+
+            If Settings::antialiasedFontDilationEnabled() is true, when rendering non-smoothed
+            text (and if CSS hasn't opted into antialiased mode), use custom font dilation
+            parameters, chosen using a light/medium/dark heuristic, to make this text
+            match more closely with LCD-smoothed text.
+
+            * page/Settings.cpp:
+            (WebCore::Settings::Settings):
+            (WebCore::Settings::setAntialiasedFontDilationEnabled): Set global state
+            in FontCascade (which can't easily get at Settings). This it not ideal,
+            but is temporary.
+            * page/Settings.h:
+            (WebCore::Settings::antialiasedFontDilationEnabled):
+            * page/Settings.in: Can't autogenerate this setting any more.
+            * platform/graphics/FontCascade.cpp:
+            (WebCore::FontCascade::setAntialiasedFontDilationEnabled): Set the global.
+            (WebCore::FontCascade::antialiasedFontDilationEnabled):
+            * platform/graphics/FontCascade.h:
+            * platform/graphics/GraphicsContext.cpp:
+            (WebCore::GraphicsContext::setAntialiasedFontDilationEnabled): Set graphics state
+            to say that we should do dilation of antialiased text.
+            * platform/graphics/GraphicsContext.h:
+            (WebCore::GraphicsContextState::GraphicsContextState):
+            (WebCore::GraphicsContext::antialiasedFontDilationEnabled):
+            * platform/graphics/ca/mac/PlatformCALayerMac.mm:
+            (PlatformCALayer::drawLayerContents): If the layer is not opaque, enable the
+            dilated text code path.
+            * platform/graphics/cocoa/FontCascadeCocoa.mm:
+            (WebCore::dilationSizeForTextColor): Heuristic (values chosen empirically) to
+            computed custom dilation based on foreground color.
+            (WebCore::FontCascade::drawGlyphs): Set the custom dilation parameters, and the
+            antialiasing state if we're not doing smoothing, and CSS hasn't opted into the
+            antialiased path.
+            * platform/spi/cg/CoreGraphicsSPI.h: New SPI.
