This checkin has preliminary API (in flux, definitely changes still
to be made) and implementation for a new "Scenes & Transitions" feature.
The current implementation allows you to define different Scenes
(via layout resource IDs or callbacks) and Transitions to be used when
changing to those scenes. By default, scene changes will use AutoTransition,
which generally does the right thing.
There are no overview docs or tutorials yet. The best way to learn how things
work is to see the code for the various tests in
frameworks/base/tests/TransitionTests.
Expect the API to change. Expect the implementation to change (mostly to add
more functionality). Expect bugs, but tell me if things do not work
as expected.

The invalidate region when the clip bounds are set needs to encompass both
the old clip bounds and the new bounds, to make sure that the right area
of the view gets erased as well as drawn.
Also, we need to keep our own internal copy of the bounds, not just use the
instance passed into the setter.

Implement new mode for status bar, allowing it to overlay
windows that use WM.LP.FLAG_FULLSCREEN, and introduce
transparency.
No gesture is implemented yet, for now the auto-hiding
status bar can be shown using a debugging intent.
android.intent.action.HIDEYBARS
The auto-hiding status bar hides 3 seconds after shown,
or 3 seconds after last user-interaction with the shade.

Adding a view to an overlay usually entails removing the
view from its current parent, if it has one. ViewOverlay.add() will
do this automatically. At the same time, it will check to see whether
the parent view is in a different global location than the overlay's
host view, and will adjust the added view accordingly. This enables
the caller to simply toss a view into an overlay and have it end up
at the same global position on the screen.
the problem is that the current code doesn't bother to check whether
the old parent is attached. If that parent has been removed from the
view hierarchy before this overlay operation, then it will show up as
being at (0,0) in the window, not its old location. This results in the
view being mis-positioned in the overaly.
Fix is simple: if the view's old parent is not attached, simply remove
it from that parent before adding it to the overlay; don't try to compensate
for its position which is based on wrong information.

A bug in FolderEditText or DynamicLayout (b/8600683) was causing
the 'rectangle' parameter passed to scrollToRectOrFocus() to be
roughly 1000 feet to the right of the screen.
This bug is normally masked because the focus found in
mLastScrolledFocus never matches the new focus and consequently
the misleading 'rectangle' is nulled. However, on the first
time in to scrollToRectOrFocus when returning to Launcher
from another app, mLastScrolledFocus is null and the code
skips over the place where 'rectangle' is nulled. Without this
clearing it was determined that 'rectangle' was outside the viewable
area and scrolling not required. This is bug 8547155.
This change causes even null values of mLastScrollFocus to be
compared to the new focus thus masking the bug in all situations.
Bug 8600683 will be fixed in a separate CL.
Fixes bug 8547155.

The last frame of an animation stays stuck on the screen for a couple of frames.
Specifically, the "Quick Contact" animation that animates the picture
closed (fades/scales it away) animates all the way to the end... then hangs there
briefly before being taken down.
The problem is a rendering bug where we correctly detect that a DisplayList
has nothing to draw (since the last frame is completely transparent, alpha==0),
but incorrectly ignore the fact that we cleared the transparent-background
window prior to not-drawing that DisplayList. When we detect that there's
nothing to draw, we don't bother swapping buffers. So even though we drew
the right thing (clearing the buffer), we didn't actually post the buffer to the
screen.
This change factors in both the clear and the draw to decide when to swap buffers.

The new implementation more accurately tracks the velocity
of flings and takes care to avoid obvious discontinuities.
The main goal is for a fling to appear to be a linear
extension of the movement already in progress. The minimum
fling velocity is set to ensure that flings appear to be
fairly smooth despite being discretized.
Use sequences of repeated key events instead of individual
down/up events to represent continuous motions in one
direction which can be helpful for stopping flings at boundaries
such as when flinging the cursor position within a text view.
Compute the movement thresholds based on the physical
size of the touch pad, if known. If not known, we assume a
nominal size.
Support stopping flings with a tap just like we do for
normal touch events elsewhere in the framework.
Moved the detection of ASSIST swipes into the InputReader
where it belongs. These swipes must be detected globally
to ensure consistent behavior across the all applications.
Added a custom protocol in EventHub to enable input device
drivers to override the timestamp of the following events
in a packet. This change enables input device drivers
that have a better idea of when an input event was actually
generated to pass this information to the input system.
Particularly useful with uinput.

The trackball to dpad synthesis was using the MotionEvent's precision
field to determine a threshold for movement but the calculations
involved did not actually make sense for any value of precision
less than 2.0. This worked fine before since the InputReader
hardcodes the trackball's precision to 6.
Injected trackball events may have a different precision which can
result in the thresholds being set inappropriately. For example,
it was not possible to move focus by one unit at a time when
the precision was set to 1.0.
The old code was probably using precision as a way to set a
threshold based on the trackball moving by some minimum number
of physical ticks, in this case 2. But the code will work just
as well if we set an absolute threshold based on distance
traveled given that the input system is already expected to
normalize the trackball movements before delivering them to the
application.
So stop using precision.

Redesigned how ViewRootImpl delivers input events to views,
the IME and to native activities to fix several issues.
The prior change to make IME input event delegation use
InputChannels failed to take into account that InputMethodManager
is a singleton attached to the main looper whereas UI may be
attached to any looper. Consequently interactions with the
InputChannel might occur on the wrong thread. Fixed this
problem by checking the current thread and posting input
events or callbacks to the correct looper when necessary.
NativeActivity has also been broken for a while because the
default event handling logic for joysticks and touch navigation
was unable to dispatch events back into the native activity.
In particular, this meant that DPad synthesis from touch navigation
would not work in any native activity. The plan is to fix
this problem by passing all events through ViewRootImpl as usual
then forwarding them to native activity as needed. This should
greatly simplify IME pre-dispatch and system key handling
and make everything more robust overall.
Fixed issues related to when input events are synthesized.
In particular, added a more robust mechanism to ensure that
synthetic events are canceled appropriately when we discover
that events are no longer being resynthesized (because the
application or IME is handling or dropping them).
The new design is structured as a pipeline with a chain of
responsibility consisting of InputStage objects. Each InputStage
is responsible for some part of handling each input event
such as dispatching to the view hierarchy or to the IME.
As a stage processes an input event, it has the option of
finishing the event, forwarding the event to the next stage
or handling the event asynchronously. Some queueing logic
takes care to ensure that events are forwarded downstream in
the correct order even if they are handled out of order
by a given stage.
Cleaned up the InputMethodManager singleton initialization logic
to make it clearer that it must be attached to the main looper.
We don't actually need to pass this looper around.
Deleted the LatencyTimer class since no one uses it and we have
better ways of measuring latency these days using systrace.
Added a hidden helper to Looper to determine whether the current
thread is the indicated Looper thread.
Note: NativeActivity's IME dispatch is broken by this patch.
This will be fixed later in another patch.
