Instead of having this struct (in addition to SkYUVSizeInfo), perhaps we should
have a single struct (SkYUVInfo) that contains all of this and is used by
everyone?

-        SkISize fSize[3];
-        size_t  fSizeInMemory[3];
-        size_t  fRowBytes[3];
+        YUVSizeInfo fSizeInfo;
         SkYUVColorSpace fColorSpace;
