[Rd] Italics in svg output display as bold

[Prof Brian Ripley]

Sorry, but package Cairo is not what we were talking about here, and 
problem with that on Windowsare known (to several of us at least).

The report was about the svg() device in Unix-alike R.  Reports on the 
Cairo package need to be sent to its maintainer (Simon Urbanek) and 
I'e removed the misleading PR#.
