Yeah, this is definitely cool. The CVS version of librsvg (as opposed to 
version 2.0.1 shipped with GNOME 2) is quite capable of viewing a good 
percentage of the SVGs out there and if we can have any gdk-pixbuf aware 
application transparently support (to some degree) WMF, EMF, and SVG, we'll 
win big.

We in the AbiWord team have been working on WMF and EMF support too. WMF 
supports writing to both SVG, PNG, and other formats. EMF is in the works, 
but will support at least a SVG output. I'm thinking that perhaps an 
intermediate SVG representation might be preferable here, since WMF and EMF 
are also vector formats.

Please send any patches of RSVG to me. I'd love for something like this to 
get included. cinamod hotmail com or doml appligent com  You can also 
contact me for any WMF or EMF related issues.

On a side note, is there any way to get the list of available importer and 
export formats, via mime-type or extension or something? This would be 
really useful for a few things that we AbiWord developers want to do, and a 
few planned extensions to librsvg's "test-rsvg" program, which I plan on 
shipping separately. Ideally, I'd like to say something similar to 
"svg2raster --type=image/png file.svg"
