GTK Header bar on Godot builds for Linux.

[vvvvvvitor]

I made a mockup of what the header bar for GTK applications could look in Godot, I'm no graphic designer, it's just an idea I've had for a while. Godot's UI looks really different when compared to GTK's, this could help bring some consistent and also free some screen space. I've read that Wayland is adding support for client-side window decorations so this may be achievable.

If this feature is implemented then please make it optional. There are still plenty of Linux desktops out there that use conventional title bars.

Yes, it would be optional, just like OSX's titlebar.

For the reference: Godot 4 already have similarly looking extend-to-title option on macOS, it might eventually have it on Linux as well. Godot do not use GTK, and adding it as a dependency just for the title bar is not acceptable, so it will look differently anyway.

That's why I suggested doing it with Wayland's client-side decorations
