It was previously the case that a view marked ~DRAWN must be
invalidated correctly already, so we would not mark any flags.
Display lists added new logic such that an undrawn node must still
be checked to see if its cache has been marked invalid. If not,
we must mark it invalid to make sure that a future rendering call
will cause the view to refresh its display list, thus refreshing its
child node tree's display lists, since that's where the invalidate
call must have originated.

The SurfaceHolder provided by the wallpaper service was not reporting
the correct size in getSurfaceFrame(). This broke an optimization in
the ImageWallpaper. The old code happened to work because calling
lockCanvas on the SurfaceHolder with a null dirty rectangle happened
to have the side-effect of updating the SurfaceHolder's surface frame
size field because it passed mSurfaceFrame as the dirty rect, causing
mSurfaceFrame to be set to the size of the region to be drawn.
However, relying on this side-effect is wrong. Among other things,
the dirty region could actually be smaller than the surface frame.
This patch fixes WallpaperService, SurfaceView and ViewRoot to ensure
that the surface frame size is always set explicitly and is not modified
by calls to lockCanvas.

Bug #3385247
- The layer's alpha was interpreted in the wrong range 0..255 instead of 0..1
- 9-patches would not correctly dirty the layer region, the generated mesh
was incorrect

requestLayout() and forceLayout() should force the INVALIDATED
flag to be set, which causes a view's display list to be regenerated
on the next drawing operation. This is necessary when containers change
due to layout requests.

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.

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. Views may setSystemUiVisibility() to recommend that
the system chrome (status bar or other UI) show or hide
itself. (This functionality was previously available only
via the FLAG_FULLSCREEN window flag for some SystemUI
implementations.)
2. Views may register a OnSystemUiVisibilityChangedListener
on a view, and find out when the system UI actually
appears or disappears, allowing apps to coordinate the
appearance of their own UI if desired.
