video initialization

I've seen several locations where video can be initialized. The initialization function in winWindow.cc states that most init routines have been moved to DisplayDevice::init(). But, having looked at that in platformVideo.cc I only see:

void DisplayDevice::init()
{
	smCurrentRes = Resolution( 0, 0, 0 );
	smIsFullScreen = false;
}

What's the appropriate place for initializing smoothing, antialiasing, and the like?

Thanks.
