Do not treat a window that is animating as being onscreen until it
has been drawn. The indication that a window was "gone" was occurring
too soon resulting in windows appearing before the status bar came
back and having to be drawn twice, with and without the status bar.
By waiting for the window to be drawn the status bar appears and the
window does not have to get redrawn.

1. The screen magnification feature was implemented entirely as a part of the accessibility
manager. To achieve that the window manager had to implement a bunch of hooks for an
external client to observe its internal state. This was problematic since it dilutes
the window manager interface and allows code that is deeply coupled with the window
manager to reside outside of it. Also the observer callbacks were IPCs which cannot
be called with the window manager's lock held. To avoid that the window manager had
to post messages requesting notification of interested parties which makes the code
consuming the callbacks to run asynchronously of the window manager. This causes timing
issues and adds unnecessary complexity.
Now the magnification logic is split in two halves. The first half that is responsible
to track the magnified portion of the screen and serve as a policy which windows can be
magnified and it is a part of the window manager. This part exposes higher level APIs
allowing interested parties with the right permissions to control the magnification
of a given display. The APIs also allow a client to be registered for callbacks on
interesting changes such as resize of the magnified region, etc. This part servers
as a mediator between magnification controllers and the window manager.
The second half is a controller that is responsible to drive the magnification
state based on touch interactions. It also presents a highlight when magnified to
suggest the magnified potion of the screen. The controller is responsible for auto
zooming out in case the user context changes - rotation, new actitivity. The controller
also auto pans if a dialog appears and it does not interesect the magnified frame.
bug:7410464
2. By design screen magnification and touch exploration work separately and together. If
magnification is enabled the user sees a larger version of the widgets and a sub section
of the screen content. Accessibility services use the introspection APIs to "see" what
is on the screen so they can speak it, navigate to the next item in response to a
gesture, etc. Hence, the information returned to accessibility services has to reflect
what a sighted user would see on the screen. Therefore, if the screen is magnified
we need to adjust the bounds and position of the infos describing views in a magnified
window such that the info bounds are equivalent to what the user sees.
To improve performance we keep accessibility node info caches in the client process.
However, when magnification state changes we have to clear these caches since the
bounds of the cached infos no longer reflect the screen content which just got smaller
or larger.
This patch propagates not only the window scale as before but also the X/Y pan and the
bounds of the magnified portion of the screen to the introspected app. This information
is used to adjust the bounds of the node infos coming from this window such that the
reported bounds are the same as the user sees not as the app thinks they are. Note that
if magnification is enabled we zoom the content and pan it along the X and Y axis. Also
recomputed is the isVisibleToUser property of the reported info since in a magnified
state the user sees a subset of the window content and the views not in the magnified
viewport should be reported as not visible to the user.

...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.

This change is the initial check in of the screen magnification
feature. This feature enables magnification of the screen via
global gestures (assuming it has been enabled from settings)
to allow a low vision user to efficiently use an Android device.
Interaction model:
1. Triple tap toggles permanent screen magnification which is magnifying
the area around the location of the triple tap. One can think of the
location of the triple tap as the center of the magnified viewport.
For example, a triple tap when not magnified would magnify the screen
and leave it in a magnified state. A triple tapping when magnified would
clear magnification and leave the screen in a not magnified state.
2. Triple tap and hold would magnify the screen if not magnified and enable
viewport dragging mode until the finger goes up. One can think of this
mode as a way to move the magnified viewport since the area around the
moving finger will be magnified to fit the screen. For example, if the
screen was not magnified and the user triple taps and holds the screen
would magnify and the viewport will follow the user's finger. When the
finger goes up the screen will clear zoom out. If the same user interaction
is performed when the screen is magnified, the viewport movement will
be the same but when the finger goes up the screen will stay magnified.
In other words, the initial magnified state is sticky.
3. Pinching with any number of additional fingers when viewport dragging
is enabled, i.e. the user triple tapped and holds, would adjust the
magnification scale which will become the current default magnification
scale. The next time the user magnifies the same magnification scale
would be used.
4. When in a permanent magnified state the user can use two or more fingers
to pan the viewport. Note that in this mode the content is panned as
opposed to the viewport dragging mode in which the viewport is moved.
5. When in a permanent magnified state the user can use three or more
fingers to change the magnification scale which will become the current
default magnification scale. The next time the user magnifies the same
magnification scale would be used.
6. The magnification scale will be persisted in settings and in the cloud.
Note: Since two fingers are used to pan the content in a permanently magnified
state no other two finger gestures in touch exploration or applications
will work unless the uses zooms out to normal state where all gestures
works as expected. This is an intentional tradeoff to allow efficient
panning since in a permanently magnified state this would be the dominant
action to be performed.
Design:
1. The window manager exposes APIs for setting accessibility transformation
which is a scale and offsets for X and Y axis. The window manager queries
the window policy for which windows will not be magnified. For example,
the IME windows and the navigation bar are not magnified including windows
that are attached to them.
2. The accessibility features such a screen magnification and touch
exploration are now impemented as a sequence of transformations on the
event stream. The accessibility manager service may request each
of these features or both. The behavior of the features is not changed
based on the fact that another one is enabled.
3. The screen magnifier keeps a viewport of the content that is magnified
which is surrounded by a glow in a magnified state. Interactions outside
of the viewport are delegated directly to the application without
interpretation. For example, a triple tap on the letter 'a' of the IME
would type three letters instead of toggling magnified state. The viewport
is updated on screen rotation and on window transitions. For example,
when the IME pops up the viewport shrinks.
4. The glow around the viewport is implemented as a special type of window
that does not take input focus, cannot be touched, is laid out in the
screen coordiates with width and height matching these of the screen.
When the magnified region changes the root view of the window draws the
hightlight but the size of the window does not change - unless a rotation
happens. All changes in the viewport size or showing or hiding it are
animated.
5. The viewport is encapsulated in a class that knows how to show,
hide, and resize the viewport - potentially animating that.
This class uses the new animation framework for animations.
6. The magnification is handled by a magnification controller that
keeps track of the current trnasformation to be applied to the screen
content and the desired such. If these two are not the same it is
responsibility of the magnification controller to reconcile them by
potentially animating the transition from one to the other.
7. A dipslay content observer wathces for winodw transitions, screen
rotations, and when a rectange on the screen has been reqeusted. This
class is responsible for handling interesting state changes such
as changing the viewport bounds on IME pop up or screen rotation,
panning the content to make a requested rectangle visible on the
screen, etc.
8. To implement viewport updates the window manger was updated with APIs
to watch for window transitions and when a rectangle has been requested
on the screen. These APIs are protected by a signature level permission.
Also a parcelable and poolable window info class has been added with
APIs for getting the window info given the window token. This enables
getting some useful information about a window. There APIs are also
signature protected.

Three problems fixed:
1. When one Activity took over for another Activity not all of the
starting window state was being copied over. Now copying over more
parameters.
2. When the visibility of an Activity was being changed the dummy
animation was overwriting the existing animation. If that animation
was the starting window animating then it started over when the
dummy animation was assigned. Now the dummy animation no longer
replaces an existing starting window animation.
3. The test for whether to animate away the starting window only
looked to see if the Activity had already drawn a window but did
not include the starting window. This caused the starting window
to immediately be hidden when the Activity was removed if no
windows were drawn, thereby exposing the fading window behind.
Now the starting window is included in the hasAppShownWindows test
and is animated away if it is exposed.

...or settings from lock screen
When a window is drawn, the code to determine whether it should now
be shown was calling WindowState.isReadyForDisplay(). Part of the
condition of this function is that it is not ready if a policy is
forcing the window to be hidden -- which is the case when the lock
screen is shown. As a result, we wouldn't show the window at that
point, so wouldn't tell the activity manager that the token's windows
are visibible, and wouldn't tell the lock screen to go away.
This adds a new variation WindowState.isReadyForDisplayIgnoringKeyguard(),
which is the same as the original method but ignores the policy visibility
for app windows. This allows windows to be go through the complete
path of handling when the window is finally drawn and telling the
activity manager about it, even if behind the lock screen. By making it
a separate function, we don't impact any other code that is calling the
old function and may be relying on its behavior.
Also cleaned up a little of the dumpsys output. Most important, the
new ANR section is now moved to the top, since we want
"adb shell dumpsys window" to still give a nice summary of what we
normally care about -- the window stack and important global state.
