You're not being lazy enough. All of this stuff can be easily 
implemented in one go using CreateStdDispatch, as long as you know how 
to use it. Try the attached patch.

Changelog:
Return the standard font IDispatch interface created using 
CreateStdDispatch on top of a typelib instead of manually implementing 
the necessary methods.
