Yes, like you wrote below, there were long discussions, not only in www-style. I could search the quotes, but I think you know them already since you actively took part on the discussions IIRC. All viewers I know take a fixed resolution. This is from the WebKit source code:
// We always assume 96 CSS pixels in a CSS inch. This is the cold hard truth of the Web.
// At high DPI, we may scale a CSS pixel, but the ratio of the CSS pixel to the so-called
// "absolute" CSS length units like inch and pt is always fixed and never changes.

The test works on Firefox as well as on Batik and on a local copy of WebKit here. So

Thanks, this line needs to be removed. The same for the title. Like I wrote in the comment on the SVG, I took test animate-elem-89-t as reference. This is the clincher :)

Yes, would be good to test it as well. Now that we use the same fonts on all browsers.
