Cut down on type-checking overhead

We *know* what the parent class is. There is
no point in checking every time we want to
chain up. We only do this because the
foo_parent_class that the G_DEFINE_TYPE macro
provides for us is a generic pointer. And that
is just because we don't have the C name for
the parent type available there.

Just cast things, and avoid taking type system
locks.
