// This is nasty so I'd better explain what's going on.
// The basic problem is that the synthetic mouse coordinate generated
// by DOMWindowUtils.sendMouseEvent and also the synthetic mouse coordinate
// generated internally when contextmenu events are redirected to the focused
// element are rounded to the nearest device pixel. But this rounding is done
// while the coordinates are relative to the nearest widget. When this test
// is run in the mochitest harness, the nearest widget is the main mochitest
// window, and our document can have a fractional position within that
// mochitest window. So when we round coordinates for comparison in this
// test, we need to do so very carefully, especially if the target element
// also has a fractional position within our document.
//
// For example, if the y-offset of our containing IFRAME is 100.4px,
// and the offset of our expected point is 10.3px in our document, the actual
// mouse event is dispatched to round(110.7) == 111px. This comes back
// with a clientY of round(111 - 100.4) == round(10.6) == 11. This is not
// equal to round(10.3) as you might expect.
