* We have this, the instance data of the root class, PRECEDING
* the "object". This is so that Gadget objects are Gadget pointers,
* and so on. If this structure grows, it will always have o_Class
* at the end, so the you can always get it by subtracting #4 from
* the pointer returned from NewObject().
*
* This data structure is subject to change. Do not use the o_Node
* embedded structure.
