Subject Re: SVG to PNG transcoding and phaysical image sizes

Hi Werner,
    Yes, text renders differently on different platforms, and yes this is
very annoying, and no I don't know of anyway to work around it.
It causes all sorts of headaches with the Batik automated testing system
(it more or less means that you need a set of reference images for
every platform).
