Helvetica is being included because it is the default font for the
device. Changes for R 2.3.0 will mean that it is possible to specify
something non-standard like Lucida as the default font for the device.
However, it's going to require more work to get rid of Zapf Dingbats
because R always includes it for drawing small circles.
