Vector2 Math

Is the math here correct? `origin` was modified before calculating `thanDistance`
I tried to load this TMX and build some walls. But my body always goes through wall#13 and stick to the bottom side of wall#9

```XML

```

```Java
map = new TmxMap("test.tmx");
world = new World(map.Width, map.Height);
body = world.Create(100, 100, 20, 20);

foreach(var obj in map.ObjectGroups["Obstacles"].Objects) {
walls.Add(world.Create((float)obj.X, (float)obj.Y, (float)obj.Width, (float)obj.Height));
}
```
