Visit the URL. Now try to zoom. It doesn't. (Which is too bad, because it would be a great way to show off SVG!)

This is probably the same bug as the SVG dpi scaling one.

Install http://ted.mielczarek.org/code/mozilla/fullpagezoom.xpi or evaluate
this in Firefox's error console to zoom:
top.window.opener.getBrowser().markupDocumentViewer.fullZoom = 1.5
Open http://de.wikipedia.org/wiki/Bild:Svg.svg and zoom in. Note that the svg
image gets larger, but instead of being redrawn at the higher resolution, it
looks like zooming in a bitmap image, with zigzag lines.
Now open just the svg image itself:
http://upload.wikimedia.org/wikipedia/commons/1/15/Svg.svg
Zooming only affects the text "SVG" (zooming in makes it larger).
Most other examples like http://www.croczilla.com/svg/samples/tiger/tiger.svg
doesn't react at all to zooming.
But this one actually gets smaller when zooming in:

You _are_ zooming in a bitmap image. The image on the description page is a png.

If you zoom out enough they get cut off at the bottom and right edge.

I see this Bug also when using Demo from this Blog
http://blog.vlad1.com/archives/2007/07/28/149/
Maybe we should file a new Bug, because this one is about fully broken zooming
Reduced testcase for getting smaller when zooming in:
<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:svg="http://www.w3.org/2000/svg" id="canvas">
<rect id="background-rect" x="0%" y="0%" width="100%" height="100%" fill="#aaaaaa"/>
</svg>

Please hold off on filing more bugs about this until Bug 370006 gets fixed.

Tim's fix for bug 370006 seems to have fixed this.

Yes, RESOLVED FIXED. http://upload.wikimedia.org/wikipedia/de/e/e2/SVG-Logo.svg is still showing problems, though. (It doesn't zoom, instead it moves towards the bottom-right corner.) Looks like percentage-sized SVGs cause problems.

I'm using the latest build and when I zoom in (Ctrl-+) or zoom out (Ctrl--) the SVG image size doesn't change, however it moves from left to right or vice versa.
