Do you want me to run `cargo fmt` on it?

I have a hunch that some linux compositors already apply double-buffering, so this could be effectively adding a sort-of triple buffering.

I also need this since I need to be able to detect when the window is minimized/un-minimized for my audio plugin host engine.

Also, I made `self` in `NotificationHandler::thread_init` mutable so I can actually use my `mpsc::Sender` to send a message to my GUI.

Hmm, yeah, it's more of a compiler than a plugin development framework. Perhaps it can go in the Low Level Programming Languages section.

Oh yeah, forgot about this PR. I'll just go ahead and merge it.
