MaxTo is pretty close. I didn't come across this one in my travels. It does support the ability to ensure windows don't go beyond a certain region. But the problem I see with this app is you can't define the region size and where it's located. It only gives you an option to vertically / horizontally split evenly in sections. Like, cutting your screen in half, and then in half again. Not so much picking the size and area. Really close tho!
