Detailed Description
Input handler for the CVG format.The CVG format is the native file format of wxArt2d. It's a XML format and each a2dCanvasObject is able to load its data from CVG. There's no specification of the CVG, please have a look into the DoLoad methods of the a2dCanvasObject derived classes to see details.
In general the following is done.
- each a2dObject has a2dObject::Save() and a2dObject::Load() as a start for serialisation.
- a2dObject::DoLoad and a2dObject::DoSave() methods are virtual and should be implemented to save also the data of the derived classes.
- Saving is a two pass process, in order to first write all XML attributes of an object and next its NON attribute data and nested objects.
- one always needs to call derivedFrom::DoLoad in the implementation of a Doload()
- one always needs to call derivedFrom::DoSave in the implementation of a DoSave()
- multiple referenced objects are written only by refid attribute. When loading the file, those references are resolved.

reading a CVG document and add the contents as children to a given a2dCanvasObject parent.
This can be used to include a CVG document in an existing document. Also clipboard action might use this.
