By using the Accessibility APIs. I imagine the core is implemented pretty similarly to Slate as I think there are only a couple ways to implement window management features. It is pretty hacky in parts. For example, some windows have an absolute minimum size that they can't be resized beyond, so I have some logic that figures that out and deals with it. The hiding/showing of windows is also not as robust as I would like, but it works. There are a lot of other examples where I have added things based on observation, rather than documentation.
