Are we? ;) This setting was for the old Quartz device (long time ago). It has no effect for the new Quartz device which is provided by R and not the GUI - in fact that device doesn't even have an option for placement (partially because the new Quartz device is backend-agnostic so such setting makes no sense in general - let's say for PDF output). Because the new Quartz device is part of R, this won't change until both the GUI and R agree on some way to communicate the setting.

There are two issues here: the preference pane setting should go since it has no effect. As for Quartz, it should allow a way to set the window location and probably use something analogous to the Cocoa default setting except we can't let it set the size (because that is set by the quartz() function).
