- Restore test of hidden to isGoneForLayoutLw(), without that
we return false when setAppVisibility(true) is called which leads
to early layout of windows. Particulary on return from full screen
to non-full we lay out once before recognizing that the status bar
should be back and then again once the status bar appears causing
a jump. Fixes bug 6470541.
- Add a new test for configuration size changes to gone or hidden
windows. This forces a layout call to these windows which informs
them of the new size even though they are not shown until later.
In particular this keeps windows that were in the background
during a rotation from using their old boundaries on return.
Fixes bug 6615859.
- Consolidate WindowState.mConfiguration tests into WindowState.

Activity manager now updates window manager's current user id
directly and immediately rather than waiting for a broadcast
update. Window manager passes this through policy to the
KeyguardViewMediator and into LockPatternUtils. LockPatternUtils
no longer goes to Activity to get the current user id if it finds
that its local id is non-default.

This change removes the test for hidden when deciding whether to
do a layout. So layout begins as soon as hiddenRequested occurs.
Since hidden is cleared when animations starts considering hidden
in the layout decision will delay layout until it is too late.
In particular we were not executing a relayout on return to an
activity even though the screen had been rotated while away.

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.

The purpose of this change is to remove direct reliance on
SurfaceFlinger for describing the size and characteristics of
displays.
This patch also starts to make a distinction between logical displays
and physical display devices. Currently, the window manager owns
the concept of a logical display whereas the new display
manager owns the concept of a physical display device.

The Starting window was being made visible early because the app
token had the dummy animation set. When the real animation started
the Starting window picked it up and became transparent causing
the underlying window to become visible again => jank.
Fixes bug 6691421.
Change-Id: I95fe88d2887760e6da3adedeb6be300eb6755283
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.

of AppWindowTokens to keep track of the apps in Z order while

The status bar and navigation bar are two completely separate
elements, with their own semantics. The system bar now classifies
itself as a navigation bar, since that is really how it behaves.
This required rewriting the HDMI resizing code, so that it is
all done by PhoneWindowManager since that is what is responsible
for the size of the navigation bar (and thus now system bar). This
actually gets rid of a fair amount of code, and means we can also
do the same thing for a pure navigation bar.
Likewise the system bar now has the navigation bar ability to be
hidden when requested by system UI flags. To get the behavior
we want on Xoom, we only allow the nav bar to be hidden when it
will help provide a better aspect ratio for showing widescreen
videos.
Finally the nav/system bar now animates when hidden and shown.
