any input reader timeout rather than only when a pointer gesture
is in progress.

The mapper sends a DOWN when the finger is released then starts
a short timer. If the finger is not pressed again before the timer
elapses, then the mapper sends an UP to complete the tap. If the
finger is pressed again then the mapper starts sending MOVEs
as part of a drag.
Double/triple taps work as intended because we also start watching
for a new tap when the finger is pressed again. If a new tap
occurs the old tap is also finished. So each individual finger
short press/release cycle constitutes a distinct tap.

Added a new PointerIcon API (hidden for now) for loading
pointer icons.
Fixed a starvation problem in the native Looper's sendMessage
implementation which caused new messages to be posted ahead
of old messages sent with sendMessageDelayed.
Redesigned the touch pad gestures to be defined in terms of
more fluid finger / spot movements. The objective is to reinforce
the natural mapping between fingers and spots which means there
must not be any discontinuities in spot motion relative to
the fingers.
Removed the SpotController stub and folded its responsibilities
into PointerController.

Refactored PointerController to extract the surface management
code to a new component called a SpriteController so that it can
be used to move finger tracking spots around the screen as well.
The SpriteController is designed to fully decouple the client from
any latency introduced by surface transactions and drawing.
All sprite updates are performed asynchronously on the Looper using
a copy of the sprite state.
Added a stub SpotController implementation for touch pad UX.
It will be implemented in a subsequent patch.
Fixed a little bug in pointer orientation changes when entering
DISPLAY_ORIENTATION_90 the x offset was clobbered.

Some drivers report individual finger updates one at a time
instead of all at once. When 10 fingers are down, this can
cause the framework to have to handle 10 times as many events
each with 10 times as much data. Applications like
PointerLocation would get significantly bogged down by all
of the redundant samples.
This change coalesces samples that are closely spaced in time,
before they are dispatched, as part of the motion event batching
protocol.
Increased the size of the InputChannel shared memory buffer so
that applications can catch up faster if they accumulate a
backlog of samples.
Change-Id: Ibc6abf8af027d9003011ac75caa12941080caba3
This enlarges the window of opportunity for batching to
encompass time spent for the window to become ready (while it is
busy processing the last event).

Also be more careful about canceling fallback keys during focus
transitions, when the application handles the key, or when the
policy decides to do something different.
Fixed a crash due to JNI CallObjectMethod returning an undefined
value (not null) when an exception is thrown.
Fixed a crash due to the policy trying to create a Dialog for
recent apps on the dispatcher thread. It should happen on the
policy's Looper instead.

1. Single finger tap performs a click.
2. Single finger movement moves the pointer (hovers).
3. Button press plus movement performs click or drag.
While dragging, the pointer follows the finger that is moving
fastest. This is important if there are additional fingers
down on the touch pad for the purpose of applying force
to an integrated button underneath.
4. Two fingers near each other moving in the same direction
are coalesced as a swipe gesture under the pointer.
5. Two or more fingers moving in arbitrary directions are
transformed into touches in the vicinity of the pointer.
This makes scale/zoom and rotate gestures possible.
Added a native VelocityTracker implementation to enable intelligent
switching of the active pointer during drags.

Added the concept of pointer properties in a MotionEvent.
This is currently used to track the pointer tool type to enable
applications to distinguish finger touches from a stylus.
Button states are also reported to application as part of touch events.
There are no new actions for detecting changes in button states.
The application should instead query the button state from the
MotionEvent and take appropriate action as needed.
A good time to check the button state is on ACTION_DOWN.
As a side-effect, applications that do not support multiple buttons
will treat primary, secondary and tertiary buttons identically
for all touch events.
The back button on the mouse is mapped to KEYCODE_BACK
and the forward button is mapped to KEYCODE_FORWARD.
Added basic plumbing for the secondary mouse button to invoke
the context menu, particularly in lists.
Added clamp and split methods on MotionEvent to take care of
common filtering operations so we don't have them scattered
in multiple places across the framework.

First step of improving app screen size compatibility mode. When
running in compat mode, an application's windows are scaled up on
the screen rather than being small with 1:1 pixels.
Currently we scale the application to fill the entire screen, so
don't use an even pixel scaling. Though this may have some
negative impact on the appearance (it looks okay to me), it has a
big benefit of allowing us to now treat these apps as normal
full-screens apps and do the normal transition animations as you
move in and out and around in them.
This introduces fun stuff in the input system to take care of
modifying pointer coordinates to account for the app window
surface scaling. The input dispatcher is told about the scale
that is being applied to each window and, when there is one,
adjusts pointer events appropriately as they are being sent
to the transport.
Also modified is CompatibilityInfo, which has been greatly
simplified to not be so insane and incomprehendible. It is
now simple -- when constructed it determines if the given app
is compatible with the current screen size and density, and
that is that.
There are new APIs on ActivityManagerService to put applications
that we would traditionally consider compatible with larger screens
in compatibility mode. This is the start of a facility to have
a UI affordance for a user to switch apps in and out of
compatibility.
To test switching of modes, there is a new variation of the "am"
command to do this: am screen-compat [on|off] [package]
This mode switching has the fundamentals of restarting activities
when it is changed, though the state still needs to be persisted
and the overall mode switch cleaned up.
For the few small apps I have tested, things mostly seem to be
working well. I know of one problem with the text selection
handles being drawn at the wrong position because at some point
the window offset is being scaled incorrectly. There are
probably other similar issues around the interaction between
two windows because the different window coordinate spaces are
done in a hacky way instead of being formally integrated into
the window manager layout process.

In Honeycomb we introduced navigation controls in the status
bar, for xlarge devices without physical buttons. What about
phones? The status bar is pretty cramped already, and
besides, it's at the top of the display most of the time,
not at the bottom where your thumb is likely to be.
Enter the navigation bar. It's a new window type that
appears atop almost everything (including the keyguard); the
window manager subtracts its rectangle from the default
visible rectangle of other windows (including the status bar
and notification shade).
However, it behaves (on phones) like the status bar in that
applications that request fullscreen windows can get access
to those pixels. Well, almost; they need cooperation from
the navigation bar implementation to make the navbar
disappear, just like the status bar.
The current SystemUI implementation of the navigation bar on
phones is still rough, but it has the basics:
+ back, home, and menu keys (NB: we're showing menu all the
time right now because checking the api level of the
package owning the top window is currently a poor
indicator of whether the app requires the menu key)
+ it tries to stick to the same physical end of the device,
regardless of device orientation (on a phone, this is
the strip of land closest to the microphone)

This patch adds a mechanism for capturing, filtering, transforming
and injecting input events at a very low level before the input
dispatcher attempts to deliver them to applications. At this time,
the mechanism is only intended to be used by the accessibility
system to implement built-in system-level accessibility affordances.
The accessibility input filter is currently just a stub.
It logs the input events receives and reinjects them unchanged,
except that it transforms KEYCODE_Q into KEYCODE_Z.
Currently, the accessibility input filter is installed whenever
accessibility is enabled. We'll probably want to change that
so it only enables the input filter when a screen reader is
installed and we want touch exploration.

The input dispatcher sends a HOVER_ENTER to a window before dispatching
it any HOVER_MOVE events. For compatibility reasons, the window will
*also* receive the HOVER_MOVE. When the pointer moves into a different
window or the pointer goes down or when events are canceled for some reason,
the input dispatcher sends a HOVER_EXIT to the previously hovered window.
The view hierarchy behavior is similar. All views under the pointer
receive onHoverEvent with HOVER_ENTER followed by any number of HOVER_MOVE
events. When the pointer leaves a view, the view receives HOVER_EXIT.
Similarly, if a parent view decides to capture hover by returning true
from onHoverEvent, the hovered descendants will receive HOVER_EXIT.
The default behavior of onHoverEvent is to update the view's hovered
state by calling setHovered(true/false). Views can query their current
hovered state using isHovered().
For testing purposes, the hovered state is mapped to the pressed
drawable state. This will change in a subsequent commit with the
introduction of a new hovered drawable state.
