Results of how object transforms affect gradient rendering output in authoring tools [ACTION-2711]

Hi everyone,

As per ACTION-2711 [1] which relates to the email discussion on the public 
mailing list [2], I have checked the results of two authoring tools.

Using the test that Jeff initially posted to the list I found that both 
Illustrator and Inkscape render the gradient the same way that Firefox does (see 
illustrator_vs_inkscape_vector_gradient_output.png).

Jeff's test:
[[
<?xml version="1.0"?>
<svg xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink">
<defs>
  <linearGradient id="g1" x1="0" y1="0" x2="400" y2="50" 
gradientUnits="userSpaceOnUse">
    <stop offset="0" stop-color="red"/>
    <stop offset="0.5" stop-color="green"/>
    <stop offset="1.0" stop-color="blue"/>
  </linearGradient>
  <linearGradient id="g2" x1="0" y1="100" x2="100" y2="150" 
gradientUnits="userSpaceOnUse">
    <stop offset="0" stop-color="red"/>
    <stop offset="0.5" stop-color="green"/>
    <stop offset="1.0" stop-color="blue"/>
  </linearGradient>
</defs>

<g transform="translate(100,100)">
  <rect width="400" height="50" fill="url(#g1)" transform="scale(0.25,1)"/>
  <rect y="100" width="100" height="50" fill="url(#g2)" />
</g>

This closes ACTION-2711.

Cheers,

Anthony
