ZoomText Private Beta -  11.7.11.410

If I set my monitor to 200% zoom and then use ZoomText at 2x or greater magnification, the refresh button near the Omnibox does not magnify smoothly. The back and home buttons are still in good shape. 

In short, we need to determine how far we will magnify an image before allowing the image quality to degrade when using magnification software. Also, we need to determine if there needs to be consistency across icons.
