All geometry/drawing information is now picked up from the GTK+ theme, so replace the remaining bits (hide_buttons + title_scale) with hardcoded values from the default Adwaita theme and stop loading the metacity theme altogether. If there is a need to theme those constants again in the future, we should make them available from GTK+ where they are available for client-side decorations as well. They certainly don't justify maintaining support for a complex theme format. https://bugzilla.gnome.org/show_bug.cgi?id=741917
