Status: RESOLVED INVALID

(Core :: SVG, defect)

Hello the SVG team!

I have recently downloaded Mozilla on my Windows-XP laptop
(Mozilla/5.0, Windows; U; Windows NT 5.1; en-US; rv:1.8b, Gecko/20050210)
and I am pleased to discover that Mozilla SVG now supports gradients.
In the zip file at http://gtrebaol.free.fr/bugzilla/svg_caveats.zip,
I send you 3 SVG files not yet displayed perfectly.

I suppose that the issues 2.2 and 2.3 are the most important, because using
multi-line text is much better than separate <text> elements. I have also
experimented other features like SVG textures and Javascript animations.
I could send additional test files if you want.

I am using either Mozilla SVG or MSIE6+Adobe SVG3, and now my
scripts for Mozilla are nearly the same as for Adobe, excepted for the
keyboard input, based on <html:input> for Mozilla SVG, but more complex
to develop with the Adobe viewer because it cannot mix HTML and SVG.

Mes félicitations et bon courage!

Reproducible: Always

Steps to Reproduce:
1. load the joined file basic_shapes.svg
2. load the joined file web_app1.svg
3. load the joined file web_app2.svg 

Actual Results:  
1. caveat in basic_shapes.svg:
      - the <defs> element is inside <g style="display:none">
      - I had generated that for Mozilla SVG version 1.7.
        because it did not support gradients.
  1.1 - now the <g style="display:none"> element is useless, however
        it should not inhibit the <linearGradient> contained in <defs>.

2. caveats in web_app1.svg
   2.1 - the dashed lines are not supported yet.
   2.2 - the <tspan> element does not inherit the geometric context of the<text>
         parent, so the font size is not scaled and the position is wrong.
   2.3 - the dy="..." attribute of <tspan> has no effect.

3. crash in web_app2.svg
   3.1 - the following fragment crashes Mozilla:
         <g style="display:none">
           <defs>
              <marker>
                 ...
              </marker>
           </defs>
        </g>
       - this bug is perhaps related to the first issue described above.

Please file a seperate bug for each problem you're having.  I've already
created a bug/patch for the <tspan> propagation problem - bug 281990.

Marking bug invalid as it's a collection of bugs.
