         * iframes (painted completely blue - #0000FF) and the rest of the page is the background
         * color, which is #008000 green. When we first render the page there is an iframe in
         * the top-left corner, and when we double-tap on it it should zoom to fill the visible
         * view area leaving a little bit of space on either side. We can test for this by checking
         * a few pixels to ensure that there is some background visible on either side of the iframe.
         * Finally, when we double-tap on it to zoom out again, we need to check that the bottom of
         * the view doesn't have any checkerboarding. We can verify this by getting a few pixels and
         * checking that it is the same as the expected background color of the page, as opposed to
         * the gray shades of the checkerboard.
