It isn't a general mod like that, I fear. It was specifically made for transitioning BG to the BG2 engine. Of course, the folks over at PocketPlane might very well be making one for Planescape, so who knows?

And I agree, the tiny resolution of that particular game can be irksome.

As for it being so easy, you're right about the mod being super complicated. From the looks of it, the original way for modding it was a very very troubling experience before they went and made the streamlined EasyTutu. In fact, if the original Tutu were the only option available, I doubt I'd have had the resolve to give it a go.
