-// 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.

-   3. The command event handler for the first menuitem opens the panel.
-   4. As a menuitem was executed, the menu will roll up, hiding it.
-   5. The popuphidden event for the menu calls menuClosed which tests the popup states.
-   6. The panelOpened function tests the popup states again and hides the popup.
-   7. Once the panel's popuphidden event fires, tests are performed to see if
-      panels inside buttons and toolbarbuttons work. Each is opened and the closed.

-  This test checks that popup elements can be removed in various ways without
-  crashing. It tests two situations, one with menus that are 'separate', and
-  one with menus that are 'nested'. In each case, there are four levels of menu.
-
-  The nextTest function starts the process by opening the first menu. A set of
-  popupshown event listeners are used to open the next menu until all four are
-  showing. This last one calls removePopup to remove the menu node from the
-  tree. This should hide the popups as they are no longer in a document.
-
-  A mutation listener is triggered when the fourth menu closes by having its
-  open attribute cleared. This listener hides the third popup which causes
-  its frame to be removed. Naturally, we want to ensure that this doesn't
-  crash when the third menu is removed.

-/**
- * A BrowserView maintains state of the viewport (browser, zoom level,
- * dimensions) and the visible rectangle into the viewport, for every
- * browser it is given (cf setBrowser()).  In updates to the viewport state,
- * a BrowserView (using its TileManager) renders parts of the page quasi-
- * intelligently, with guarantees of having rendered and appended all of the
- * visible browser content (aka the "critical rectangle").
- *
- * State is characterized in large part by two rectangles (and an implicit third):
- * - Viewport: Always rooted at the origin, ie with (left, top) at (0, 0).  The
- *     width and height (right and bottom) of this rectangle are that of the
- *     current viewport, which corresponds more or less to the transformed
- *     browser content (scaled by zoom level).
- * - Visible: Corresponds to the client's viewing rectangle in viewport
- *     coordinates.  Has (top, left) corresponding to position, and width & height
- *     corresponding to the clients viewing dimensions.  Take note that the top
- *     and left of the visible rect are per-browser state, but that the width
- *     and height persist across setBrowser() calls.  This is best explained by
- *     a simple example: user views browser A, pans to position (x0, y0), switches
- *     to browser B, where she finds herself at position (x1, y1), tilts her
- *     device so that visible rectangle's width and height change, and switches
- *     back to browser A.  She expects to come back to position (x0, y0), but her
- *     device remains tilted.
- * - Critical (the implicit one): The critical rectangle is the (possibly null)
- *     intersection of the visible and viewport rectangles.  That is, it is that
- *     region of the viewport which is visible to the user.  We care about this
- *     because it tells us which region must be rendered as soon as it is dirtied.
- *     The critical rectangle is mostly state that we do not keep in BrowserView
- *     but that our TileManager maintains.
- *
- * Example rectangle state configurations:

- * This script is used for menu and popup tests. Call startPopupTests to start
- * the tests, passing an array of tests as an argument. Each test is an object
- * with the following properties:
- *   testname - name of the test
- *   test - function to call to perform the test
- *   events - a list of events that are expected to be fired in sequence
- *            as a result of calling the 'test' function. This list should be
- *            an array of strings of the form "eventtype targetid" where
- *            'eventtype' is the event type and 'targetid' is the id of
- *            target of the event. This function will be passed two
- *            arguments, the testname and the step argument.
- *            Alternatively, events may be a function which returns the array
- *            of events. This can be used when the events vary per platform.
- *   result - function to call after all the events have fired to check
- *            for additional results. May be null. This function will be
- *            passed two arguments, the testname and the step argument.
- *   steps - optional array of values. The test will be repeated for
- *           each step, passing each successive value within the array to
- *           the test and result functions
- *   autohide - if set, should be set to the id of a popup to hide after
- *              the test is complete. This is a convenience for some tests.
- *   condition - an optional function which, if it returns false, causes the
- *               test to be skipped.
- *   end - used for debugging. Set to true to stop the tests after running
- *         this one.
