Description Tim Buschtoens CLA 2011-03-02 09:46:30 EST 
The check and radio icons are visible flickering when changing state on all iOS devices, especially older ones  (iPhone/iPod) where no icon is visible for (sometimes) several seconds. Its not just the first time (where the icon is not yet loaded because the MultiCellWidget is currently not using the ImagePreloader), its every time.

This might be solved by connecting the qooxdoo image preloader with the themestore image getter. It would be a simple change and unlike the old button/atom implementation would not use the preloaders "onload" event (since we already know the images dimension).

And if that doesnt work we could use html5 cache manifest, though that would have to be created server-side: http://www.phpied.com/iphone-caching/
