/*
|
|
* for this test, we load the associated test_bug720538.html file. this file has two
|
|
* 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.
