I would like to propose a new file format based on an existing tool such as JSON (wxJSON, http://wxcode.sourceforge.net/docs/wxjson/). I think this will make the file more readable, flexible and extensible.

I actually started to replace the file based code with wxInputStream for
the component library before I realized that I had to do a lot of
cleanup to the component library objects before attempting implement
wxInputStream and wxOutputStream. I think I have the component library
object code to the point where implementing this will be reasonable
task. I still need to take a look at Dick's dsn parser and formatter
before I attack this problem again. I think the best way forward is to
leave the existing file based code alone for legacy file support and
create new load and save methods for the dsn file support. This should
make the transition from file formats a lot easier.
