Title: TUIPanel!

An NSPanel clone with auto-TUIView support that mimics the Messages.app 'Set Picture' window in 10.8.
It doesn't have sheet support yet, and I can't figure out for the life of me how to clip a view's corners (without CALayer intervention, if possible), and I think CGSPrivate died in 10.8, so I can't test window blurring.

But it works, it's non-obtrusive, and I use it in my app.
