michael@0:          * for this test, we load the associated test_bug720538.html file. this file has two
michael@0:          * iframes (painted completely blue - #0000FF) and the rest of the page is the background
michael@0:          * color, which is #008000 green. When we first render the page there is an iframe in
michael@0:          * the top-left corner, and when we double-tap on it it should zoom to fill the visible
michael@0:          * view area leaving a little bit of space on either side. We can test for this by checking
michael@0:          * a few pixels to ensure that there is some background visible on either side of the iframe.
michael@0:          * Finally, when we double-tap on it to zoom out again, we need to check that the bottom of
michael@0:          * the view doesn't have any checkerboarding. We can verify this by getting a few pixels and
michael@0:          * checking that it is the same as the expected background color of the page, as opposed to
michael@0:          * the gray shades of the checkerboard.
