Oof, this is kinda meh. We can surely make a better api on MathUtil to do this,
maybe pass it the string, the variable, and the value, and have it decide the
type internally.

thanks for the review.
I understand your intention and will file a new patch.

   MathUtil::AddToTracedValue(mask_texture_size, value);
-  value->EndArray();
+  value->EndDictionary();
 
   value->BeginArray("mask_uv_scale");
   MathUtil::AddToTracedValue(mask_uv_scale, value);
   value->EndArray();
 
   value->BeginDictionary("filters");
   filters.AsValueInto(value);
   value->EndDictionary();
 
   value->BeginArray("filters_scale");
   MathUtil::AddToTracedValue(filters_scale, value);
   value->EndArray();
 
   value->BeginDictionary("background_filters");
   background_filters.AsValueInto(value);
   value->EndDictionary();
 }
