- * Text Position
- *
- * TextPosition structure specifies coordinates within an text resource. It is used mostly
- * for saving script source position.
- *
- * Later TextPosition0 and TextPosition1 and both number types can be merged together quite easily.
- *
- * 0-based and 1-based
- *
- * Line and column numbers could be interpreted as zero-based or 1-based. Since
- * both practices coexist in WebKit source base, 'int' type should be replaced with
- * a dedicated wrapper types, so that compiler helped us with this ambiguity.
- *
- * Here we introduce 2 types of numbers: ZeroBasedNumber and OneBasedNumber and
- * 2 corresponding types of TextPosition structure. While only one type ought to be enough,
- * this is done to keep transition to the new types as transparent as possible:
- * e.g. in areas where 0-based integers are used, TextPosition0 should be introduced. This
- * way all changes will remain trackable.
- *
- * Later both number types can be merged in one type quite easily.
- *
- * For type safety and for the future type merge it is important that all operations in API
- * that accept or return integer have a name explicitly defining base of integer. For this reason
- * int-receiving constructors are hidden from API.
