Reduce the gpu load by fading the recents thumbnail to an alpha of
0.0 before the remaining animations are completed. When alpha hits
0 the gpu treats the layer as hidden and can merge the remaining
layers in time.
This is a partial fix for 7729214.

RecentsActivity screenshots are called for very quickly after
WindowStateAnimator prepareSurface(). Without enough delay the
Surface.setLayer call does not propagate to the SurfaceFlinger
and the screenshot is incorrect (black) because it stops sampling
the layers too early.
This fix calls Surface.setSize() for each sampled Surface in
screenshots. setSize forces the SurfaceFlinger to process all
transactions queued before returning from closeTransaction.

There are two things going on here:
(1) In secondary users, some times theme information such as whether
the window is full screen opaque was not being retrieved, so the window
manager didn't know that it could hide the windows behind the app.
This would just be a performance problem, except that:
(2) There appear to be a number of applications that declare that they
are full screen opaque, when in fact they are not. Instead they are
using window surfaces with an alpha channel, and setting some pixels
in their window to a non-opaque alpha level. This will allow you to
see whatever is behind the app. If the system happens to completely
remove the windows behind the app, and somebody is filling the frame
buffer with black, then you will see what the app intends -- those
parts of its UI blended with black. If one of those cases doesn't
hold (and though we have never guaranteed they would, in practice this
is generally what happens), then you will see something else.
At any rate, if nothing else than for performance reasons, we need to
fix issue #1.
It turns out what is happening here is that the AttributeCache used
by the activity manager and window manager to retreive theme and other
information about applications has not yet been updated for multi-user.
One of the things we retrieve from this is the theme information telling
the window manager whether an application's window should be treated
as full screen opaque, allowing it to hide any windows behind it. In
the current implementation, the AttributeCache always retrieves this
information about the application as the primary user (user 0).
So, if you have an application that is installed on a secondary user but
not installed on the primary user, when the AttributeCache tries to retrieve
the requested information for it, then from the perspective of the primary user
it considers the application not installed, and is not able to retrieve that
info.
The change here makes AttributeCache multi-user aware, keeping all of its
data separately per-user, and requiring that callers now provide the user
they want to retrieve information for. Activity manager and window manager
are updated to be able to pass in the user when needed. This required some
fiddling of the window manager to have that information available -- in
particular it needs to be associated with the AppWindowToken.

After finding a window in the window list we turn around and look in
the AppWindowToken.windows list for it. If it is a child of a window
in that list we should use the parent windows index as the search
result. Instead we gave up and ended up inserting the window at the
beginning of the windows list.

Turning off animations in the Developer options creates a ValueAnimator
duration scale of 0. This is used as the denominator in RampAnimator
which, if the numerator is also 0, sets mAnimatedValue to NaN. Rounding
NaN to the nearest int produces 0 which is then assigned to
mScreenBrightness in DisplayPowerState.
A copy mistake which assigned mTransitionAnimationScale as the default
value for mAnimatorDurationScale in WindowManagerService is also
fixed here.

The gnarly stuff where we keep track of the old input method
window as if it was still there was sitting around leaving things
in a stuck state. Now we clear this out at key points in the
window manager (freezing screen, user change), and the input
method manager service is less aggressive about asking the window
manager to do it.
Also fixed a problem that was causing flickers during some
wallpaper transitions -- when we are animating two things on
top of the wallpaper and one of them disappears, we need to
make sure the wallpaper target points to whatever the current
target should be (if any), not left pointing to the old target
that has gone away.

...lockscreen sometimes and remains black / blank
The problem was that we were using the animation-side wallpaper state
in cases where it was not updated yet.
The mWallpaperTarget variable is propagated over to the animation
side when the main window manager state updates. On the animation
side, this is used by hideWallpapersLocked() to determine if the
current wallpaper should be hidden.
The problem is that various paths to hideWallpapersLocked() can
come from the layout side of the window manager instead of the
animation side. This causes the problem here because in this case
the wallpaper state may not have yet been propagated to the
animation side, so it could incorrectly decide to hide the wallpaper
because it thinks there is not a target when in fact a target is
set in the layout side. This won't get fixed until some time way
later that the layout side decides that a new window is being shown
that may need to have the wallpaper shown.
The fix here is pretty gross, but as safe as possible -- the
hideWallpapersLocked() function now uses either the animation or
layout wallpaper state depending on where the call to it is coming
from.

There was a bunch of state not being put into the dumpsys output.
In particular, the current wallpaper target of the WindowAnimator
was not being included. I think the problem is that these targets
are not being updated from the main window manager state at some
point where they need to be.

A fix yesterday for #7428221 caused a regression where new orientations would
sometimes cause a flash through black on the way to seeing the real static wallpaper.
There is a fundamental problem in WindowManagerService where we show a window before
it has all of the layout/sizing information it needs, which is the cause of the black
flash. The regression yesterday was that we are now less aggressive about layout out
hidden windows, so we won't layout the window until after the window is shown with the
incorrect sizing info.
The fix/workaround is to back off the layout logic specifically for the wallpaper,
ensuring that we will lay it out on orientation changes, even when hidden. This means that
when we finally do show it, it will already have been drawn in the correct orientation/size.

A recent change in WindowManager made background windows perform layout
(when they should really be left alone). This resulted in artifacts
where rotating the device and then going to a backgrojnd activity (launcher,
Recents) would briefly show that activity in the wrong size/orientation, then
flash to the correct one after a proper layout.
This fix is a simple workaround, leaving in the original fix that the code
change addressed (for keyguard orientation changes), while going back to the
previous (don't layout gone windows) for all other cases.

1. Sometimes unlocking the device when the IME is up and triple tapping on the keyboard
toggles screen magnification. The core reason is that when the kayguard window is
shown we hide all other windows and when it is hidden we show these windows. We did
not notify the screen magnifier for windows being shown and hidden. Also when the
windows are shown we may reassign layers to put the IME or the wallpaper in the
right Z order. The screen magnifier is now notified upon such layer reassignment
since window layers are used when computing the magnified region.
