Resource for resolution-test.svg

Chromium issue: http://code.google.com/p/chromium/issues/detail?id=119693

SVGImageCache::lookupOrCreateBitmapImageForRenderer() doesn't take transform scaling into account when calculating the image buffer size. Thus SVG images are cached at the wrong resolution and show resampling artifacts when served from cache (on page reload for example).

Open resolution-test.svg - a sharp-edged triangle is displayed.
Reload the page - the triangle is blurred (resampled from a low-res cached image).
