Except that in C# everything is defined in a class. So, if the function 
is part of a library, you'd have to either define static methods or 
instance methods. The Graphics class is sealed, so there's no means of 
defining a sub class, such as GraphicEx ...so your choices are define a 
bunch of static methods, or define a class whose constructor takes a 
pointer to a Graphics object, and offers the extended functions.

C# 3.0 offers the extension methods to get around this. It may seem like 
a pointless feature to you, but for some it is a minor convenience.
