are you sure you want to remove this? enlightenment for gl_x11 has options to
force a specific swap mode via engine options. sure it wasn't implemented for
wayland but it's a useful debug tool... especially when a driver gets buffer
age wrong and you have to force it to some sane mode (like invalidate all)
again... :)
