The eglGetSystemTimeNV extension can be used to enable profiling
in PerfHUD ES. When the delta of two calls to eglGetSystemTimeNV
equals 0, we now cancels display lists updates. This allows the
tool to redraw the same frame several times in a row to run its
analysis.
For better results profiling should only be attempted after
setting viewroot.profile_rendering to true using adb shell
setprop.

Bug #8667873
windowShouldResize means we need to layout the window, it doesn't mean
the dimensions of the surface have changed. We should only check the
width and the height. With this fix we can avoid a surface allocation
every time the window shade is opened or closed.

Bug #8833153
Display lists ops might now keep references to GL resources so they
must be destroyed when the EGL context goes away.

View.getOverlay().clear() can failed with an NPE if there are
no drawables in the overlay. Fix: add a null check before dereferencing
the mDrawables field.
Issue #8895794 getOverlay.clear() crashes if drawables were not added previously

We are prefetching accessibility node infos to minimize the number of IPC
calls when an accessibility service introspects the screen. It is however,
possible that the view we are prefetching is a child of an AbsListView whose
adapter changed its data but the AbsListView still did not perform a layout
pass to sync its children with the new adapter state. This may lead to an
exeption when trying to query for the state of a child's position. If the
data of the adapter is changed and the layout pass still not performed,
we return null for the AbsLIstView's children. When the layout pass
completes we already notify the accessibliity layer so it will be able to
refetch the children of the AbsListView.

We force an invalidate whenever a View becomes VISIBLE so there is
no need to keep the display list object while the view is either
GONE or INVISIBLE. In particular this clears the lists of references
kept by GLES20DisplayList, which helps the GC free large objects
such as Bitmaps.

Different devices have different precision, leading to different pixels
being touched during rendering operations. We need to ensure that the
dirty rect we draw with (and which gets erased on the following frame)
encompasses all possible pixels instead of some ideal rounded rectangle.
The bug from this code led to dropped-pixels artifacts on some devices,
where we'd scale a view, drawing it into some pixels, then invalidate
that same area on the next frame, but the invalidation rectangle didn't
cover the same pixels as the device drew into.
The fix is to floor() the left/top pixels and ceil() the right/bottom
pixels of the transformed invalidation rectangle.

We added APIs to allow an accessibility service to extend the
selection while moving the cursor at a given granularity such
as word, character, etc. The problem is that the traversal was
extending only the end of the selection while moving forward
and the start of the selection while moving backward. This leads
to a case in which the user cannot shrink/extend the selection
because for example instead of shrinking the end of the selection
the implementation was extending the start.
Now extending the selection moves only the selection end. This is
the same behavior as text view using a keyboard.

AbsListView is backed by an adapter. After the adapter data changes
the view sets a flag that its state is dirty and requests a layout.
If an accessibility service asks for the state of a list item at
this point, it may incur an error since the views and the adapter
are not in sync.
Now if an accessibility service queries for a list item when the
data set is changed and the item views are dirty, we pretend the
children do not exist. After the layout happens, we notify the
accessibility layer that the screen content changed so it can
refetch the views if desired (this notification mechanism is
already in place in AbsListView#handleDataChanged()).

Apps using SYSTEM_UI_FLAG_HIDE_NAVIGATION to hide the nav bar
or SYSTEM_UI_FLAG_FULLSCREEN to hide the status bar can now
opt into hideybars by also using a new public sysui flag:
View.SYSTEM_UI_FLAG_ALLOW_OVERLAY
When opting in, apps accept the fact that bars can be overlayed
over their content, but gain the ability to use the entire gesture
space - something that was not possible before, particularly when
hiding the nav bar.
Swiping from the nav bar edge of the screen will reveal the new hidey
version of the nav bar, if applicable.

Internal state must be cleared before calling any methods on the focus
host, since the method may be called again from the host and attempt to
recycle the same AccessibilityNodeInfo twice.
