RecentsActivity screenshots are called for very quickly after
WindowStateAnimator prepareSurface(). Without enough delay the
Surface.setLayer call does not propagate to the SurfaceFlinger
and the screenshot is incorrect (black) because it stops sampling
the layers too early.
This fix calls Surface.setSize() for each sampled Surface in
screenshots. setSize forces the SurfaceFlinger to process all
transactions queued before returning from closeTransaction.
Bug 7552304 fixed.

Process mode functor execution can be expensive, and cause dropped frames if it
runs between two expensive frames (when there isn't cpu time to spare). Avoid
this by delaying the process mode by an additional 4 ms every time we hit a draw

If a rotation occurred while the electron beam surface was showing,
the surface may have appeared in the wrong orientation. We fix this
problem by adjusting the transformation matrix of the electron beam
surface according to the display orientation whenever a display
transaction occurs.
The rotation itself is allowed to proceed but it is not visible
to the user. We must let this happen so that the lock screen
is correctly oriented when the screen is turned back on.
Note that the electron beam surface serves two purposes.
First, it is used to play the screen off animation.
When the animation is finished, the surface remains visible but is
solid black. Then we turn the screen off.
Second, when we turn the screen back on we leave the electron beam
surface showing until the window manager is ready to show the
new content. This prevents the user from seeing a flash of the
old content while the screen is being turned on. When everything is
ready, we dismiss the electron beam.
It's important for the electron beam to remain visible for
the entire duration from just before the screen is turned off until
after the screen is turned on and is ready to be seen. This is
why we cannot fix the bug by deferring rotation or otherwise
getting in the way of the window manager doing what it needs
to do to get the screen ready when the screen is turned on again.

There are two things going on here:
(1) In secondary users, some times theme information such as whether
the window is full screen opaque was not being retrieved, so the window
manager didn't know that it could hide the windows behind the app.
This would just be a performance problem, except that:
(2) There appear to be a number of applications that declare that they
are full screen opaque, when in fact they are not. Instead they are
using window surfaces with an alpha channel, and setting some pixels
in their window to a non-opaque alpha level. This will allow you to
see whatever is behind the app. If the system happens to completely
remove the windows behind the app, and somebody is filling the frame
buffer with black, then you will see what the app intends -- those
parts of its UI blended with black. If one of those cases doesn't
hold (and though we have never guaranteed they would, in practice this
is generally what happens), then you will see something else.
At any rate, if nothing else than for performance reasons, we need to
fix issue #1.
It turns out what is happening here is that the AttributeCache used
by the activity manager and window manager to retreive theme and other
information about applications has not yet been updated for multi-user.
One of the things we retrieve from this is the theme information telling
the window manager whether an application's window should be treated
as full screen opaque, allowing it to hide any windows behind it. In
the current implementation, the AttributeCache always retrieves this
information about the application as the primary user (user 0).
So, if you have an application that is installed on a secondary user but
not installed on the primary user, when the AttributeCache tries to retrieve
the requested information for it, then from the perspective of the primary user
it considers the application not installed, and is not able to retrieve that
info.
The change here makes AttributeCache multi-user aware, keeping all of its
data separately per-user, and requiring that callers now provide the user
they want to retrieve information for. Activity manager and window manager
are updated to be able to pass in the user when needed. This required some
fiddling of the window manager to have that information available -- in
particular it needs to be associated with the AppWindowToken.

1. A view is visible to the user if is attached to a visible window,
its visibility is VISIBLE, its alpha is not zero, all its
predecessors have visibility VISIBLE and non zero alpha, the
view is not fully covered by predecessors and is within the
screen.
The function that computes whether a view is visible for
accessibility purposes was not taking into account the
predecessors' alpha.

1. In touch exploration mode the system clicks in the center of the
accessibility focus rectangle. However, if this rectangle is only
partially shown on the window or on the screen the system may not
be able to perform the click, if the accessibility focus center
is not on the screen, or click on the wrong window, if the access
focus center is outside of the window.
This change clips the rectangle to the window bounds which and the
display bounds. This will ensure no clicks are sent to the wrong
window and no clicks are sent outside of the screen.

Bug #7391098
The existing code was doing a make current to guarantee we have a
current context. This can however fail when the surface is destroyed
which could lead to GL calls without an EGL context, and therefore
potential leaks. This change fixes the issue by using a technique
found in HardwareRenderer.destroyHardwareResources(). If the surface
is not available then we use a special 1x1 pbuffer as a way to get
a valid context.

A bug in software rendering caused animations on views that are offscreen
to not get drawn, therefore the animation doesn't continue (since old-style
animations depend on the logic in the drawing code to keep running). Fix is
to special case the isAnimating case in ViewRoot to go ahead and schedule
a traversal even if the dirty rect does not intersect with the visible region.

Bug #7385090
This change gets rid of two silly asumptions:
- That a layer needs to be cleared with opaque black (it shouldn't,
it's already cleared to transparent and the view will cover it up
with its own background)
- The the clip should be dirty at the beginning of a frame only
when the render target is opaque

This was a regression introduced by a previous CL.
- we actually need to let the layout params resolution goes all the time
as we dont have any "isResolved" state and a public API for doing its reset thru ViewGroup.
The current implementation is simple and works even if it is doing sometimes a bit more
than it should really do. This is a well conscious tradeoff.
