Implement xdg-decorations

[ehopperdietzel]

Hi, I just wanted to thank you for developing this project. It's such a clever solution! Do you plan to provide client-side decorations or implement the xdg-decoration protocol? That would be really nice since compositors would be able to know if windows are not decorated.

And yeah this project seems great!

Client side/xdg decorations are planned yes, just a bit lower on the priority list for now, I'd like to address some existing bugs first. But it shouldn't be too difficult to add.
