test case (requires island.svg)

# Overview

When I use an SVG image with the img tag and set its width to 100%, the image will look pixellated (as if it were a scaled-up bitmap) if the image's container is wider than the SVG's own size (set with `width`, `height`, and `viewBox`).


# Steps to reproduce

1) View attached test case in a browser window.
2) Ensure that the browser window is significantly wider than 300 pixels. Most normal desktop browser window widths should work.


# Actual results

The black stroke looks fuzzy and pixellated.


# Expected results

The black stroke should look smoothly scaled up as in the browsers that display this OK (see below)


# Build Date & Platform

The first WebKit nightly that I noticed this behavior in is 5.1.3 (7534.53.10, r111220).


# Additional Builds and Platforms

Safari 5.1.3 (7534.53.10)/OS X: OK
Safari/iOS 5.1 (9B176):         OK
Chrome 17.0.963.79/OS X:        FAIL
Chrome 17.0.963.79/Vista:       FAIL
Firefox 11.0/OS X:              OK
IE 9.0.8112.16421/Vista:        OK
