    Well there's always mention of an argument type in a function header, and
we still respect that argument.

Its just that so many widgets are containers for other widgets, and they all
take GtkWidget * arguments.

So I guess the bottom line you are looking for is, when calling a function
and passing it an argument that was already declared as the correct type,
there is no need to redundantly cast it again.
