[oats-sig] Ang: Re: Ang: Re: Ang: Re: Ang: Re: wmf to svg conversion

Matt,

OK, I've glued a little application together employing the components
outlined below (going through xaml as an intermediate step)

http://www.3point14.com/pub/WMF_to_SVG_binaries.zip
http://www.3point14.com/pub/WMF_to_SVG_sources.zip

binaries require the Microsoft .NET Framework 3.5 installed
sources can be built using Visual C# 2008 Express
