Hi Jon,

A different question (on the same part of the spec):

Consider the example

<svg xmlns="http://www.w3.org/2000/svg" width="400" height="300">
   <g transform="scale(2)">
      <rect x="25%" y="25%" width="50%" height="50%" fill="green"/>

Should the green rectangle be a box in the center of the viewport, 
one-quarter its size, or should it be the same size as the viewport, with 
its upper-left corner in the center?

The spec indicates (if I understand it properly) it should be the former, 
since percentage measures are calculated relative to the dimensions of the 
nearest viewport (SVG 7.10), ignoring the transform on the <g> element. But 
both the Adobe and Batik viewers render it as the latter.

How are percentages to be calculated? If either viewer followed the spec, 
I'd say the other was wrong....
