- we want functions like isEmpty() to return true if NANs are
involved in the Rect
- also clean-up the intersect familly of calls
- minor cleanup in the int32_t Rect as well
These played a role in http://b/5331198.

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.

Fixed problem in AudioTrack::restoreTrack_l() causing a permanent
failure if the IAudioTrack interface to AudioFlinger could not be
restored at the first attempt.

Calculate the velocity using the most recent touch sample as the
point of reference instead of the oldest. This change more heavily
weights recent touch samples and reduces the sample time window
used for calculation. This significantly improves the accuracy
of fling gesture detection.

The list of directories to skip are configurable via setprop.
The main motivation is that some test data folder takes long time
to scan, and media scanner may compete for CPU time against perf
tests therefore skewing the results.

External storage volumes that were emulated+encrypted needed to have
their encryption mapping removed so that it doesn't try to encrypt the
volume after formatting them.
This just wires through an argument through vold, and assumes that vold
will do the right thing even if there is no encryption mapping set.

When the A2DP headset is connected, there is a possible
race condition when the audio tracks are moved from
the mixer thread attached to the speaker output to the thread
attached to A2DP output.
As the request to clear the stream type to output mapping cache in
the client process is asynchronous, it is possible that the flag
indicating to the client audio track to re-create the IAudioTrack
on the new thread is processed before the cache is invalidated.
In this case, the track will be attached to the old thread and
music will continue playing over the device speaker instead of being
redirected to A2DP headset.

AudioTrack::stop() is not synchronous, so a stop() followed
by flush(), which is synchronous, will not always report
a playhead position of 0 after being called.
This CL adds a flag to mark a track as flushed, and report the
correct playhead position in this state.
Bug 5217011 has been created to address the real issue in the
future, where flush could be made synchronous, to properly
address bug 4364249.

This is the test for Gralloc buffers based encoding.
contains a combination of two main changes:
1. GL based encoding tests added to SurfaceMediaSource_test
2. SurfaceMediaSource ::read() colorformat
The SurfaceMediaSource::getformat() sets it to OMX_COLOR_FormatAndroidOpaque.
The omx encoder needs to interpret that colorformat and reads the format
from the Gralloc buffers directly

This change makes SurfaceFlinger always use the
GRALLOC_USAGE_HW_COMPOSER usage bit when allocating buffers that may be
passed to the HWComposer.

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.

This change fixes the NATIVE_WINDOW_QUEUES_TO_WINDOW_COMPOSER query of
Surface and SurfaceTextureClient. Surface now uses the inherited
SurfaceTextureClient implementation of this query. SurfaceTextureClient
now queries SurfaceFlinger to determine whether buffers that are queued
to its ISurfaceTexture will be sent to SurfaceFlinger (as opposed to
some other process).

we were not reseting mCurrentTexture in some situations
which in turn caused dequeueBuffers() return a
"FREE" buffer that was also current.
Very often it was harmless, but it created a race with
updateTexImage() which could cause the following
queueBuffers() to fail.
