e041716ba1 Make GraphicBuffer a RefBase

3e010f3138 Add createTJunctionFreeRegion
T-junction free regions are useful for rendering regions with various
geometric transformations, and the Region's span-ordered, sorted rect
list supports T-junction free storage without modification.

This approach creates a T-junction free region by splitting each
rectangle that is part of a vertical T-junction. This approach is two
pass (up and down) so that divisions can trickle up/down to other
adjacent spans.

This change moves the frame time history tracking code out of Layer and into a

3ab68558fa change how we store Region data internally
We used to keep the bounds of the region as a
separate rectangle. Instead we now store it as the last
element of the Vector<> of Rects.

This has the benefit of being slightly more efficient when
copying regions and reduces the overhead of small regions,
but more importantly will allow us to export the underlaying
SharedBuffer (eventually).

8683fca395 improve [un]marshalling of non-binder objects
this change introduces a new class LightFlattenable<> which is
a protocol to flatten simple objects that don't require
binders or file descriptors; the benefit of this protocol is that
it doesn't require the objects to have a virtual table and give us
a consitant way of doing this.

we also introduce an implementation of this protocol for
POD structures, LightFlattenablePod<>.

Parcel has been update to handle this protocol automatically.

Sensor, Rect, Point and Region now use this new protocol.

ef19414bd8 Transfer HWC release fences to BufferQueue
After a HWC set, each SurfaceFlinger Layer retrieves the release fence
HWC returned and gives it to the layer's SurfaceTexture. The
SurfaceTexture accumulates the fences into a merged fence until the
next updateTexImage, then passes the merged fence to the BufferQueue
in releaseBuffer.

In a follow-on change, BufferQueue will return the fence along with
the buffer slot in dequeueBuffer. For now, dequeueBuffer waits for the
fence to signal before returning.

The releaseFence default value for BufferQueue::releaseBuffer() is
temporary to avoid transient build breaks with a multi-project
checkin. It'll disappear in the next change.

a18829ab23 Accurately track the sequence numbers of batched events.
Instead of sending finished signals immediately when appending to
a batch, record the chain of sequence numbers that were part of
the batch and then send finished signals all at once when done.
This change helps the dispatcher keep track of the true state
of the application and can improve ANR detection slightly.

f0490c94d0 Implement batching of input events on the consumer side.
To support this feature, the input dispatcher now allows input
events to be acknowledged out-of-order.  As a result, the
consumer can choose to defer handling an input event from one
device (because it is building a big batch) while continuing
to handle input events from other devices.

The InputEventReceiver now sends a notification when a batch
is pending.  The ViewRoot handles this notification by scheduling
a draw on the next sync.  When the draw happens, the InputEventReceiver
is instructed to consume all pending batched input events, the
input event queue is fully processed (as much as possible),
and then the ViewRoot performs traversals as usual.

With these changes in place, the input dispatch latency is
consistently less than one frame as long as the application itself
isn't stalled.  Input events are delivered to the application
as soon as possible and are handled as soon as possible.  In practice,
it is no longer possible for an application to build up a huge
backlog of touch events.

This is part of a series of changes to improve input system pipelining.

73aaf0d8d2 Velocity Tracker II: The Revenge of Velocity Tracker
Bug: 5265529

Rewrote the velocity tracker to fit a polynomial curve
to pointer movements using least squares linear regression.
The velocity is simply the first derivative of this polynomial.

Clients can also obtain an Estimator that describes the
complete terms of the estimating polynomial including
the coefficient of determination which provides a measure
of the quality of the fit (confidence).

Enhanced PointerLocation to display the movement curve predicted
by the estimator in addition to the velocity vector.

By default, the algorithm computes a 2nd degree (quadratic)
polynomial based on a 100ms recent history horizon.

ecc7adef2e Input system bug fixes, particularly for stylus.
Bug: 5049148

Finished stylus support, including support for indirect stylus
and mouse tools.

Added TILT axis.  When stylus tilt X/Y is available, it is transformed
into an orientation and tilt inclination which is a more convenient
representation and a simpler extension to the exiting API.

Touch devices now only report touch data using a single input
source.  Previously touch devices in pointer mode would report
both absolute touch pad data and cooked pointer gestures.
Now we just pick one.  The touch device switches modes as needed
when the focused application enables/disables pointer gestures.
This change greatly simplifies the code and reduces the load
on the input dispatcher.

Fixed an incorrect assumption that the value of ABS_(MT_)DISTANCE
would be zero whenever the stylus was in direct contact.  It appears
that the correct way to determine whether the stylus is in direct
contact (rather than hovering) is by checking for a non-zero
reported pressure.

Added code to read the initial state of tool buttons and axis values
when the input devices are initialized or reset.  This fixes
problems where the input mapper state might have the wrong initial
state.

Moved responsibility for cancelling pending inputs (keys down,
touches, etc.) to the InputDispatcher by sending it a device reset
notification.  This frees the InputReader from having to synthesize
events during reset, which was cumbersome and somewhat brittle
to begin with.

Consolidated more of the common accumulator logic from
SingleTouchInputMapper and MultiTouchInputMapper into
TouchInputMapper.

Improved the PointerLocation output.

5873ce46ad Refactor input reader to add stylus support.
Bug: 5064702

Introduced the concept of an InputListener to further decouple
the InputReader from the InputDispatcher.  The InputListener
exposes just the minimum interface that the InputReader needs
to communicate with the outside world.  The InputReader
passes arguments to the InputListener by reference, which makes
it easy to queue them up.

Consolidated all of the InputReader locks into one simple global
Mutex.  The reason this wasn't done before was due to potential
re-entrance in outbound calls to the InputDispatcher.  To fix this,
the InputReader now queues up all of the events it wants to send
using a QueuedInputListener, then flushes them outside of the
critical section after all of the event processing is finished.
Removing all of the InputMapper locks greatly simplifies the
implementation.

Added tests for new stylus features such as buttons, tool types,
and hovering.

Added some helpers to BitSet32 to handle common code patterns
like finding the first marked bit and clearing it.

Fixed a bug in VelocityTracker where the wrong pointer trace
could get cleared when handling ACTION_POINTER_DOWN.  Oops.

Changed PointerCoords so it no longer stores useless zero
axis values.  Removed editAxisValue because it is not very
useful when all zero value axes are absent and therefore
cannot be edited in place.

Added dispatch of stylus hover events.

Added support for distance and tool types.

acb7b5dfc8 Adding SurfaceEncoder for encoding FilterFrames
Adding SurfaceEncoder which can be used to encode
custom frame data. In a sense, it is reverse
of what SurfaceTexture does.

SurfaceEncoder takes in frames from a native window and
passes them to an encoder, thus acting like a MediaSource.
It uses GRAlloc buffers underneath for passing data.
The client side sets the geometry, format in the beginning,
which cannot be changed while the recording is going on.

Currently, there is no common pixel format that both
GRAlloc and HAL understand.
Also, the encoder cannot encode using the data from the GRAlloc
buffers.

The SurfaceEncoder_test examines mainly the buffer passage
since true encoding cannot be done at this point.
SimpleDummyRecorder 'reads' the frames in the same thread
as the start(), whereas DummyRecorder 'reads' in a separate
thread much like the MPEG4Writer. The test with DummyRecorder
is much closer to the real encoding implementation.
