It was not a good idea to introduce a fake root MemoryObjectInfo.
It makes a problem when we visit an object without its own MemoryObjectType.

Example: RenderBox has a global pointer to a hash map.
HashMap doesn't have its own object type because it is a generic container.
It will inherit object type from the fake root memory object info.
The same could happen for another container in another class with other MemoryObjectType.

This fact forces me to create custom process method for root objects
because they need to have their own MemoryObjectInfo with customisable memory object type.

patch to follow.
