Bug: 5062011
Previously, each GLES20DisplayList would hold onto an instance of
GLES20RecordingCanvas. In turn, each GLES20RecordingCanvas
held onto an SkWriter with a 16Kb buffer along with several other
objects. With one display list per view and hundreds of views,
the overhead could add up to a few megabytes.
Ensured that the GLES20RecordingCanvas is reset as soon as
the display list has been constructed, thereby promptly freeing
the 16Kb buffer.
Changed GLES20DisplayList so that it acquires a GLES20RecordingCanvas
from a pool as needed and recycles it when done.
Removed some dead code and cruft related to the construction of
GLES20Canvas objects in general. Some code was written with the
assumption that the underlying renderer object could change
behind the scenes or might be lazily constructed, but that isn't
actually the case so we can simplify things.
Removed an unnecessary weak reference from GLES20DisplayList
to the View. It isn't actually used anywhere.
Fixed a bug in GLES20DisplayList where isValid() would return
true while the display list was being recorded. This is incorrect
because the native display list might not actually exist. Worse,
even if the native display list does exist, it is stale and
potentially refers to old Bitmaps that have been GC'd (because the
mBitmaps list was cleared when recording started).

invalidations.
This includes expand/collapse state.
Add CollapsibleActionView interface. Views can implement this to have
special behavior when they are presented as an expanding/collapsing
action view. This lets SearchView and others take care of fiddly
behavior (focus stealing; opening the IME) automatically without apps
needing to implement this themselves.

To profile the looper, run the following command:
adb shell am profile looper start <process> <file>

1. Added content description to pretty much all animals
in the zoo including buttons in the navigation bar,
notifications and status icons for battery, signal,
data, etc.
2. Rectored to avoid ovelaying views since they block
touch exploratino. In general overlaying views
cause trouble for touch exploration and accessibility
in general.
3. Avoid sending accessibility events in case the user is
touching outside of the StatauBAr panels to avoid
confusion.
4. Added records to accessibility events in the places where
this would help the presentation. So the event comes from
a given "leaf" view and its predecessor is adding a record
to the event for itself to provide more cotext. It is up
to the accessiiblity service to choose how to present that.

- cleanup public.xml
- make BiDiTest makefile non visible to the build system
- provide file for injecting the new attributes by hand

This change will be useful to create multiples instances of
HardwareRenderer outside of ViewRootImpl. This will allow
the use of hardware accelerated canvas on TextureView or
for live wallpapers.

View.setClipChidlren(false) allows children to draw outside of their containers.
But logic in ViewGroup.invalidateChildInParent() constrains the invalidation
rectangle to the bounds of the parent, making the flag useless in some situations.
Avoid intersecting the dirty rect with the parent bounds when the parent
is set to not clip its children.

Also:
. Remove backward compatibility Group class now that AppsCustomizePagedView has been updated.

Minor optimization in setFrame(), to force recreation of
a view's display list only when the actual size of the view has
changed.

It was done so we would have the name "ViewRoot" available for a
public API. However, the name "ViewAncestor" just makes no sense.
So instead, change it to ViewRootImpl.

1. Seperated touch exploration to be a seperate setting rather being
magically enabled by the system of accessiiblity is on the there
is at leas one accessibility service that speaks enabled. Now
there is a setting for requesting touch exploration but still the
system will enabled it only if that makes sense i.e. accessibility
is on and one accessibility service that speaks is enabled.
2. Added public API for checking of touch exploration is enabled.
3. Added description attribute in accessibility service declaration
which will be shown to the user before enabling the service.
4. Added API for quick cloning of AccessibilityNodeInfo.
5. Added clone functionality to SparseArray, SparseIntArray, and
SparseBooleanArray.

1. Updated all integet properties of AccessibilityRecord to be set to -1
so this is a clue to the client that this property is irrelevant for
the current event type.

The edge slop feature was added a long time ago for a specific
device that had severe non-linear touch response issues near
the edges of its touch screen. The feature is not useful on
modern hardware that is property calibrated.
