ListView child views with transientState (setHasTransientState(true)) are not
handled correctly when the data set changes, such as when an item is added
or removed. The problem is that the transient views are cached by their
position, but this position is out of sync between the ListView and the adapter
until the ListView layout process is complete.
A better way, which unfortunately only works on ListViews with stable IDs, is
to cache the views by their itemID instead, and to use that ID to determine when
and where to reuse/retrieve a transient view during the ListView layout.

It is useful, particularly in animations, to be able to add a view, or at
least some graphics, on top of a view. For example, to have a child of a layout
fade away, we might want to remove the child from that layout and then fade it out
gradually. Meanwhile, we have to have a place to put that view where it will be
drawn. We could do this in the content container sometimes, but this is not a
reliable workaround in the general case, and may obscure other siblings/parents of
the layout/view in the hierarchy. A better approach would be to place a view/graphic
temporarily in the layout itself.
This feature adds the ability to add one or more Views and Drawables to an "overlay"
layer, after which the view will handle drawing that extra content when it redraws itself.

In general, calling requestLayout() during layout is a Bad Idea.
However, ListView does this during the normal course of its layout, as it
removes and adds views during layout. However, it handles this properly,
ensuring that the views in its hierarchy are all measured and laid out
properly by the time its layout process is done.
A previous fix to the request-during-layout issue attempted to distinguish
the correct from incorrect behavior by checking whether views had been properly
laid out since the requestLayout() call, and making sure the views were
visible in the hierarchy (parented, attached, and !GONE), since otherwise
the views would not be laid out, the flags wouldn't be cleared, and requests
are superfluous anyway. However, this logic only checked whether the
requesting views were GONE, whereas the check should include the entire
parent hierarchy of the views (since a view with a GONE parent is still not
visible to the user).
This fix adds that additional check and cleans up other parts of the previous
code, such as not bothering to post() requests that occur during the second
layout pass unless those requests are also valid (coming from visible views).

While the inset scrollbars may change padding and how backgrounds are
drawn such that an otherwise opaque view is no longer opaque. However,
OUTSIDE_OVERLAY scrollbars don't change the padding and should not
affect the determination of opacity.

the behavior of getGenerationId(). This simply restores the old

of the shell process.

The window manager now maintains and reports a new formal
"overscan insets" for each window, much like the existing
content and visible insets. This is used to correctly
position the various UI elements in the various combination
of layout options. In particular, this allows us to have
an activity that is using fitSystemWindows to have the content
of its UI extend out to the visible content part of the screen
while still positioning its fixed UI elements inside the
standard content rect (and the entire window extending all
the way into the overscan area to fill the screen as desired).
Okay, maybe that is not written so clearly. Well, it made
my head hurt too, so suffer!
The key thing is that windows now need to know about three
rectangles: the overall rectangle of the window, the rectangle
inside of the overscan area, and the rectangle inside of the
content area. The FLAG_LAYOUT_IN_OVERSCAN option controls
whether the second rectangle is pushed out to fill the entire
overscan area.
Also did some improvements to debug dumping in the window
manager.

Drawing was previously wrapped in a try/finally block which was silently
swallowing user code exceptions. For instance, if a View throws a
NullPointerException in its onDraw() method, the previous implementation
would silently crash in native code.
This change extracts the section that builds display lists into a new
method that does not contain any try/finally block.
In addition, this change logs any exception thrown while drawing
display lists.
