User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060907 Minefield/3.0a1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060907 Minefield/3.0a1

Placed text inside a group element with a transform="scale(0.9,1)"  to produce squashed text.  Displays fine on Firefox 1.5,2 but is distorted on minefield.  Example:

<svg id="test" width="100%" height="100%"
  viewBox="0 0 1000 500"
  xmlns="http://www.w3.org/2000/svg">
<g fill="rgb(9,39,105)" font-weight="bold" font-family="Arial">
 <g stroke="rgb(9,39,105)" stroke-width="2" transform="scale(0.58,1)">
 <text font-size="100px" text-anchor="middle" x="540" y="100">MOZILLA</text>
 <text font-size="120px" text-anchor="middle" x="540" y="200">FIREFOX</text>
 </g>

 <g fill="rgb(11,79,157)" stroke="rgb(11,79,157)" stroke-width="2"  transform="scale(0.9,1)">
  <text font-size="100px" text-anchor="middle" x="340" y="300">SVG TEXT</text>
 </g>
</g>
</svg>


Reproducible: Always

Steps to Reproduce:
1.Open above SVG with Minefield
2.
3.

Actual Results:  
Text outline and fill do not align.

Expected Results:  
Stroke and fill should align.  Note Firefox 1.5 and 2 are not perfect but very close.  Minefield is way off.

I can confirm that the strokes and fills in the testcase don't line up.  I'm using Mac trunk.

Comment 3

[Robert Longson [:longsonr]]

Determining when this regressed on the trunk would be helpful if anyone has the time or inclination to do that.

WFM - linux trunk.  Likely problems with the cairo platform font backends.

[Jeff Schiller]

I think this is another testcase for this problem: http://www.codedread.com/svghead2.svg.  The shadow fill is way off of the stroke in the reflected text.

Yay, this now works for me in the latest trunk 20070103, thanks to the cairo uplift, I guess.

[Jonathan Watt [:jwatt]]

It now works for me too. If anyone's still sees any problems, please reopen.
