Normally, the X server infers the initial screen size based on any connected outputs. However, if no outputs are connected, the X server picks a default screen size of 1024 x 768. This option overrides the default screen size to use when no outputs are connected. In contrast to the "Virtual" Display SubSection entry, which applies unconditionally, "NoOutputInitialSize" is only used if no outputs are detected when the X server starts.
Parse this option in the new exported helper function xf86AssignNoOutputInitialSize(), so that other XFree86 loadable drivers can use it, even if they don't use xf86InitialConfiguration().
