The point of using a zoomed out preview is that the effect can be
applied on the zoomed out view. Otherwise it would be unreasonably slow.
So there's no equivalent of draw_region() because you aren't working
directly with pixel regions here. You are usually using the
gimp_drawable_get_sub_thumbnail() function to retrieve a scaled view of
the pixel data and then apply your effect on these preview pixels.
