For regular elements, whenever -moz-appearance is used, the CSS background is
ignored. Root elements were behaving specially, and the background color also
needed to be adjusted.
For example, for Windows 7, we have the following CSS rule;
```
:root {
background-color: transparent;
-moz-appearance: -moz-win-borderless-glass;
}
```
This change makes the root element more consistent with other elements, so the
extra `background-color: transparent` declaration is no longer necessary.
This change does not let content documents opt out of forced opaqueness:
Root content documents still get an opaque background color from an existing
check further down in this method.

On macOS, the OS window always comes with an opaque background for top level
windows. This is the case even if Gecko determines the root element of the
window to be transparent: Ever since bug 1162649, nsChildView/nsCocoaWindow
ignore calls to SetTransparencyMode for top level windows and always stay opaque.
Returning true from nsChildView::WidgetPaintsBackground() lets us indicate that
we do not need an opaque backstop color to be added at the bottom of the display
list. This backstop color would interfere with vibrant -moz-appearance rendering
under the new vibrancy model.
WidgetPaintsBackground() is only called in one place, in ComputeBackstopColor():
```
nscolor PresShell::ComputeBackstopColor(nsView* aDisplayRoot) {
nsIWidget* widget = aDisplayRoot->GetWidget();
if (widget && (widget->GetTransparencyMode() != eTransparencyOpaque ||
widget->WidgetPaintsBackground())) {
// Within a transparent widget, so the backstop color must be
// totally transparent.
return NS_RGBA(0, 0, 0, 0);
}
// Within an opaque widget (or no widget at all), so the backstop
// color must be totally opaque. The user's default background
// as reported by the prescontext is guaranteed to be opaque.
return GetDefaultBackgroundColorToDraw();
}
```
On Windows 7, the widget returns eTransparencyBorderlessGlass from
GetTransparencyMode(), which also avoids the backstop color.

Drawing vibrancy fill colors was necessary in the past because we were erasing
the fill color that was drawn by the system, through our override of the
drawRect method of our NSVisualEffectView subclass.
However, starting with changeset be263e3d8bdfc0b6c072ffad2736999b9652d036
(from bug 1491445), we no longer override drawRect. Moreover, since the switch
to Core Animation, there is no way to clear the system's vibrancy fill drawing.
So we don't need to draw the vibrancy fill color any more. In fact, we should
stop drawing it, because now we're double-drawing it.
The fill color is very translucent so the double-drawing is not visually obvious.

This static method is assumed to have the same signature as the type's constructor,
and so we must have an implementation of ComputePerFrameKey for each constructor
a display item provides that is called by MakeDisplayItem. Notably this excludes
the MakeClone constructor for a lot of items.
There is a default varargs implementation on nsDisplayItem which everyone
inherits by default, so types which previously didn't overload this method
still don't need to.
Providing an implementation of ComputePerFrameKey on some display item type
shadows the varargs implementation, so one doesn't need to worry about overloading
one constructor but forgetting about another -- if you do, the compiler will only
see the overload and complain that the signature doesn't match.
One slightly annoying result of this is that display items which previously
inherited an overloaded implementation from a superclass now must provide
their own manual implementations. Although as far as I could tell, all of
those cases had a trivial implementation of key=0 (the super class supported
custom keys but the subclasses didn't make use of it).
In those cases I just hardcoded key=0, but it's possible that it would be
better to call into the superclass' implementation to be more robust to changes.

The help view copies strings from the main menubar. When we moved the original DTD string
to ftl, there were performance implications for using it in browser.xhtml, so it was
only added once needed. The help view copies attributes from the items in the main menubar's
help menu, and so didn't copy the label for this item, resulting in the broken
behaviour.
To fix this, it's enough to have the string in the markup. As we've moved the other strings
into menubar.ftl, I'm taking the opportunity to move this string there, too, next to its
sibling string to report deceptive sites.

Add test annotations to the ReftestManifest and TestResolver. For example, a
test description from the TestResolver might now contain 'skip-if': 'skiaContent';
similar to the content provided for manifestparser tests; this will allow
'mach test-info report' to filter tests based on reftest manifest test
annotations.
Also add the referenced-test field which identifies the test file associated
with test entries for reference files; this will allow test-verify to
run the correct reftest when only the reference file has been modified.

I found that this test sometime would fail on the try server, and the reason is that the child document doesn't be activated correctly even if we have called `synthesizeMouseAtCenter()`.
In order to reduce the dependency of other modules, which might affect synthesizing event, we should use `notifyUserGestureActivation` to ensure that we indeed activate the document.
