+ FontCascade::typesettingFeatures() is not privy to font-variant-* nor font-feature-settings
+ https://bugs.webkit.org/show_bug.cgi?id=149775
+
+ Reviewed by Darin Adler.
+
+ This patch has two pieces:
+
+ We used to have a boolean, enableLigatures, which affected how we perform shaping in both our
+ simple and complex text codepaths. However, in this brave new world of font-feature-settings
+ and font-variant-*, there are many properties which may affect shaping (and multiple kinds
+ of ligatures). This patch renames this boolean to requiresShaping, and teaches it about all
+ the various properties which affect text shaping.
+
+ Similarly, one of the places which used this enableLigatures boolean was to tell CoreText
+ if it should disable ligatures. However, we now have much finer-grained control over
+ ligatures during font creation. This patch moves the responsibility of dictating which
+ font features should be enabled entirely to the Font. Therefore, getCFStringAttributes()
+ doesn't know anything about ligatures anymore; the logic inside font creation is used
+ instead.
+
+ An added benefit of moving all the font feature logic to one place is that we can implement
+ the feature resolution algorithm described in the CSS3 fonts spec. This patch adds a test to
+ makes sure that text-rendering, font-feature-settings, and font-variant-* play together
+ nicely.
