About this test[edit]

To the RC lurkers who stumble upon this: in an effort to speed page loading times in the Azure skin (which uses image backgrounds), we're currently testing replacing the current PNGs and JPGs which range from 100-200KB each, with vectorized SVGs made by antgeth that are only about 10KB each. However, SVGs are newer technology and not fully supported across all browsers, so we need to ensure compatibility before putting them live on the site. (And we need a proper fallback for older browsers like IE8 and lower).

Notably, there's already a glitch when rendering these in Firefox (documented here and here) - it seems FF rasterizes SVGs at their original resolution before scaling them (whereas other browsers losslessly scale them on the fly). The result is a very blurry sunburst in Firefox, but I'm looking into ways of fixing this with ant, since there may be a few workarounds.

Anyway, if you have any concerns/feedback about how the backgrounds look on the test page, leave it here - especially if your browser has any problems with them. Thanks! -CapitalQtalk ♪ 16:46, 31 March 2013 (EDT)

Ant has made the initial resolution of the SVGs 5x larger (only increasing the filesize by around 1-2KB each), which has resolved the Firefox issue. -CapitalQtalk ♪ 22:33, 31 March 2013 (EDT)
