Restrict saved surface to launcher start (ACTION_MAIN&CATEGORY_
LAUNCHER), or there is no intent at all (eg. task being brought to
front). If the intent is something else, likely the app is going
to show some specific page or view, instead of what's left last time.
This solves problems like the launcher shortcuts on DeckClock,
each of them is a different intent and will show one specific
view regardless of last states. Another example is Chrome tab
opened directly by action VIEW to open some URL.
(Note that this doesn't solve the problem with Chrome homescreen
shortcuts, it will still start with saved surface (if Chrome
is already open). This is because the shortcut is a trampoline
activity that starts the real chrome tab activity, but when
the trampoline is started, the whole task is already brought
to front, and ChromeTab could become visible with the task
before we actually start it.)

Original commit:
Dispatch a11y events in separate thread.
Moves the IPCs into a separate thread, where they should affect
jank a lot less.

Some existing apps treat drawable visibility notifications as a signal
to crossfade from a placeholder to the new image for the purposes of
scrolling onscreen via a recycling collection view or similar. Since
dispatchVisibilityAggregated is now called for window visibility
changes and ImageView informs its drawable of the visiblity change,
the extra call triggers a repeat fade-in in some existing apps when
you return them to visibility.
These apps should pay attention to the second parameter of
Drawable#setVisible, which signals that animations should not restart
in response to a visibility change. Updating to targetSdkVersion=24+
will enable the new behavior.

This value is used to convert ACTION_SCROLL axis values into raw
pixel distances.
CP of ag/1333603 from master to feldspar-dev. New method is @hide and
@SystemApi in this version. In master, it's part of the new public
API, but feldspar will launch before O.

First, we fix the transparent region computation to use the order as the
drawing. Previously, it is using the tree traverse order, not the draw order.
Second, add the y offset for any view with positive z value, this will allow
some space for shadow.

This type behaves like a normal TYPE_APPLICATION, except that WM
will always wait for it to be drawn before starting a transition.
WM always waits for TYPE_BASE_APPLICATION (main window), but for
TYPE_APPLICATION, it only waits if the window relayouts to visible
and gets a surface before the main window is drawn. If main window
itself is ready very fast, transition could start without the other
window.

As discussed in ag/1192965/ we have a special case for rotation
animation selection in launch from double tap. This was set to
ROTATION_ANIMATION_CROSSFADE as the goal was just to avoid
ROTATION_ANIMATION_ROTATE on the viewfinder surface and
seamless rotation in launch scenarios was initially descoped. Now we
are aiming at fixing this though, and ROTATION_ANIMATION_CROSSFADE
does not quality for seamless rotation. ROTATION_ANIMATION_JUMPCUT
also would not be a good choice because in the situation that the
rotation occurs before the app starting window appears, then we would
jump cut from unrotated wallpaper to rotated app, I think we want
a crossfade in this scenario. To this end introduce and use a new @hide constant
ROTATION_ANIMATION_SEAMLESS which qualifies for seamless but falls back
to CROSSFADE if seamless can't occur.
