Another approach may be to use hooks (see ?setHook). The plot.new function already has a hook, so you could do your option #1 automatically by setting that hook.
Better would be if all the graphics device functions had hooks (or a common hook), then you could set that hook to set your graphics parameters and they would be set every time a new graphics device was started. -- Gregory (Greg) L.
