Feature request: macOS VoiceOver integration
Gtk applications using the Quartz backend are not accessible using the system's screen reader VoiceOver. Only their menus are accessible, if they use gtk-mac-application or Gio menus.
To be accessible, they should implement the NSAccessibility protocol. I don't know if this should be done via an AT-SPI to VoiceOver bridge, by interacting with ATK in process or by any ad-hock mean.
