Lost the functionality to find the real type pointed by a pointer.
Ex: a osg::Node pointer point on a osg::Group, if I look for information
on the pointer type, the introspection say it is a "osg::Node*".
But if I want information on the pointed type,
the introspection must return the "osg::Group".
This bug come from the osgIntrospection::Value::Ptr_instance_box::ptype() function.
In the original version, this function use the member "Instance_base *inst_"
like this :
typeof(*static_cast<Instance<T> *>(inst_)->_data)
But in the new version, this function use the template argument "T":
typeof(typename remove_pointer<T>::type)
This is a good meta-programming use, but here we need a dynamic request.
Moreover the "typeof" macro define in "Reflection" header accept only a type in parameter with the new version.
fix:
Add the macro "typeofvalue" in "Reflection" header which accept a value or a type in parameter.
Restore original code in osgIntrospection::Value::Ptr_instance_box::ptype() function.
