When printing a plot to and svg file, text intended to be in italics is rendered
in bold (svg file viewed using both Safari 3.2.1 and Firefox 2.0.0.9.

For example, try viewing the test.svg file generated by

svg("test.svg", width=4,4,8)
plot.new(); text(0.5,0.5,labels=expression(italic("This should be in
italics")))
dev.off()
