+
+ Update WHLSL to Metal tester with semantics
+ https://bugs.webkit.org/show_bug.cgi?id=190416
+ <rdar://problem/45145139>
+
+ Reviewed by Myles Maxfield.
+
+ A few small changes to the WHLSL to Metal tools:
+ - Make it compile by adding some missing JS files :)
+ - Add semantics to the default shader
+ - Add FIXMEs to the other shaders
+ - Create an in-browser test for the WHLSLToMetal codepath
+ - Fix typos in the semantics checker
+
