+// 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.

+  This test does the following:
+   1. Opens the menu, causing the popupshown event to fire, which will call menuOpened.
+   2. Keyboard events are fired to cause the first item on the menu to be executed.
+   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.

+
+  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.
