The objective in this listener is to be more careful about the
signal processing to prevent spurious orientation changes
and to make all of the tweakable factors physically meaningful.
The calibration is defined in terms of time constants and
does not assume a particular discrete sampling rate. This is
useful because it allows us to change the accelerometer sampling
interval if desired without having to change the calibration.
Moreover, the accelerometer sampling interval can vary +/- 20ms
from one sample to the next even in normal circumstances.
Proposed orientation changes are weighted by confidence factors
that vary exponentially in relation to how close the device
is to the ideal orientation change posture (screen is vertical,
angle is exactly at the midpoint of the orientation quadrant,
and no external acceleration beside gravity). When not in an ideal
posture, the device takes proportionally longer to settle into a
new orientation state.
Added a little tool to plot the log output of the
WindowOrientationListener. Check the README for more information
about how to use it.

Bug 3381320
The tests were inconsistent between makeBlink and onDraw.
If the text is non-editable, do not draw the cursor.

Bug 3381317
Changes made in https://android-git.corp.google.com/g/#change,91880
displayed the IME onFocus. However, the test was not consistent to what
is done in touch event. textIsEditable is now checked too.

1. Remove mDeferMultiTouch in WebView, it was for testing only but
we don't need it now since we always pass MultiTouch to WebKit.
2. Remove the use of mDeferMultiTouch in DRT tests.
3. Correct the index of getX(Y) for the second touch point in the
debug string of MotionEvent.

Previously, display lists were used only if hardware acceleration
was enabled for an application (hardwareAccelerated=true) *and* if
setDrawingCacheEnabled(true) was called. This change makes the framework
use display lists for all views in an application if hardware acceleration
is enabled.
In addition, display list renderering has been optimized so that
any view's recreation of its own display list (which is necessary whenever
the visuals of that view change) will not cause any other display list
in its parent hierarchy to change. Instead, when there are any visual
changes in the hierarchy, only those views which need to have new
display list content will recreate their display lists.
This optimization works by caching display list references in each
parent display list (so the container of some child will refer to its
child's display list by a reference to the child's display list). Then when
a view needs to recreate its display list, it will do so inside the same
display list object. This will cause the content to get refreshed, but not
the reference to that content. Then when the view hierarchy is redrawn,
it will automatically pick up the new content from the old reference.
This optimization will not necessarily improve performance when applications
need to update the entire view hierarchy or redraw the entire screen, but it does
show significant improvements when redrawing only a portion of the screen,
especially when the regions that are not refreshed are complex and time-
consuming to redraw.

1. The logic for updating the higher rank fields on wrapping of
lower rank ones was incorrect. Updated that logic.
2. On reaching the min/max date the spinners did not stop
when reaching that date. Now spinners stop at min/max.
3. Fixed a couple of edge case bugs while setting the
the min and max dates of the DatePicker on the fly.
4. Restricted the scrolling/flinging to end at the min
and max dates.
