- *  - We first define what the interface really contains. This is the IDirect3DImpl structure. The

- *  - Then we predeclare our static virtual table variable, we will need its address in some
- *    methods to initialize the virtual table pointer of the returned interface objects.
- *  - Then we implement the interface methods. To match what has been declared in the header file
- *    they must take a pointer to an IDirect3D structure and we must cast it to an IDirect3DImpl so
- *    that we can manipulate the fields.
- *  - Finally we initialize the virtual table.
