Details

If a <browser> has transparent=true set, its content won't get subpixel AA (it falls back to greyscale AA). This seems to happen even if the <browser>'s parent is completely opaque. My understanding (after talking with roc) is that as long as there is an opaque layer somewhere, subpixel AA should work. In bug 620963 (and other in-content UI, like about:permissions), we want to fade the lightweight theme into the background of the page. To do this, I've setting setting the transparent attribute on the <browser> - unfortunately, having greyscale AA is a roadblock.
