Sketchy Draw

With SketchyDraw, you can create graphics.

When preserving a document, API as NSArchiver was used by the old version of this application. The thing by which this API is eliminated from macOS10.13 is announced. NSKeyedArchiver is used instead of NSArchiver in version 10.12.2~ of this application. When reading, both API is used to answer to a made document with the old version. When reading in the present, I'm moving, but it'll be predicted that it isn't possible to read any more in the future. When preserving it again, it's written in in new API, so while a reading fact can be done, I'll recommend to preserve it again.
