/********************************************************************
>   class StartDocument : public Node

Created:    17/5/93
Author:     Jim_Lynn (Xara Group Ltd) <camelotdev@xara.com>
Purpose:    This object type has no purpose other than to sit at the 
            beginning of the tree. It never has children, is not renderable
            and not selectable. It can never be deleted. There is only 
            ever one and it is always the first object in the tree. It
            exists so that object can be inserted at the head of the tree
            without the pointer from the document to the tree having to 
            be relinked - any object to be inserted at the head of the 
            tree should be inserted after the StartOfDocument object.

*********************************************************************/

class StartDocument : public Node
{
public:
    StartDocument() : Node() {};
    
    // To replace StartDocument(Node* ContextNode etc.

                  AttachNodeDirection Direction, 
                  BOOL Locked=0, 
                  BOOL Mangled=0,  
                  BOOL Marked=0, 
                  BOOL Selected=0, 
                  BOOL Renderable=0); 

    virtual UINT32 GetNodeSize() const;             // Returns size of node in bytes

    virtual BOOL IsPaper() const;               // Override func in base class

       
protected:
    
    virtual Node* SimpleCopy();

// No members, no functions, nothing
// Might need some debugging info, but that's it!

Created:    17/5/93
Author:     Jim_Lynn (Xara Group Ltd) <camelotdev@xara.com>
Purpose:    An object which is always the last object in the tree. This 
            ensures that we are always able to add objects at the end, 
            just by inserting them before the EndOfDocument object
