Bring window controls closer to Adwaita

[danirabbit]

windowcontrols button {
border-radius: 99px;
background: alpha(@text_color, 0.1);
-gtk-icon-shadow: none;
padding: 2px;
margin: 3px;
}

window {
border-radius: 9px;
}

Making the corners rounder and adding a background behind window controls would make Adwaita apps feel a lot closer to the native look

I wouldn't do it. I fear it would look too similar to the default focus highlighting for header bar buttons.
