In the case of scaled SurfaceViews with a fixed size.
It is possible for the surface layout size to change
without a change to the surface size or position. In this
case we need to inform the window manager so it can update
frames and scaling. This has presented in Camera and required
workarounds such as changing the fixed surface size to trigger
an update (leading to visual artifacts).

Move add/removeWindowCallbacks to onAttachedToWindow/onDetachedFromWindow.
There might be more than one windows in an app process, the window
callbacks need to be per window, not global.

A change was made back in ICS that prevents the view hierarchy from rendering
during window animations. Specifically, it allows the hierarchy to render once (to draw
the results of its first layout), but further drawing is suppressed at the
ViewRoot/performTraversals level until the window animation is complete.
This change was introduced to avoid jank problems that were resulting from
thrashing the GPU by issuing drawing commands from multiple processes simultaneously,
and limited the number of rendering processes to mainly the system server (and
possibly the System UI), which allowed window animations to be much smoother.
This fix contributed to another source of jank, however, in which applications
which attempt to animate when they first appear will not render any frames of
animations until the window animation is done, resulting is a snapping to the resulting
state once the window animations are complete.
Meanwhile, hardware has gotten faster and GPUs have gotten better, and it is time to
revisit this logic. This change disables the earlier fix and allows view hierarchies
to draw normally, regardless of whether window animations are taking place.

Whether acitvity window should be preserved during the relaunch is
controlled by the activity manager and the existence of
non-client-decor should not affect it. For example, docked activities
will not have non-client-decor, but we would like to preserve them
anyway.

This is achieved by not having the decor view hold onto the activity
context. Instead, we are wrapping application context, so that we can
have theme support and also have a special instance of window manager
that is aware of the phone window (the same way as activity do).
This reverts commit a5ffea3b7d.

The only time AppWindowToken.willBeHidden is used is for determining
if the app should contribute to calculating orientation. In the same
check AppWindowToken.hiddenRequested will be or-ed with willBeHiden,
so it's enough that hiddenRequested to be set.
The only place where willBeHidden is set, is right before
WMS.setAppVisibility is called, which will set hiddenRequested.
Because of this willBeHidden is unnecessary.

When there is docked stack, we want to show a "handle" through which the
user will resize the docked stack. We add it from the system process,
because we want to avoid IPC calls.

Surface should only be invalidated when surface generation changed
(which we're already doing). Window size change doesn't always imply
a surface change. During a drag-resizing action, the window size is
constantly changing but the surface remains the same. setSurface
could take 12ms+ each frame and cause frame drops.

This is adding the renderer side infrastructure to allow
rendering multiple render nodes with different threads.
This is a pre-step for decoupling a non client decor
resize reder from a content resize render.
Multiple render nodes can be added to be drawn, and to
prevent overdrawing, a content bounds area can be set

If the id is negative, it is not from Resource.
Passing the negative value to getResourcePackageName makes AssetManager dump unnecessary warning logs.
It is reasonable not to get package/type/entry information for the negative id.

Instead of letting the client render to (0,0) and moving the surface
around, put the surface at a fixed location, and let the client render
to the screen position within the surface.
This fixes the window shaking problem when resizing by dragging window's
top-left corner. The frame rect used in last draw is lagging window
manager's latest bounds for the window, moving the surface's position
would make the window's bottom-right corner appears moving (while it's
supposed to be stationary).

This changes application code behavior when the activity relaunches due
to configuration change. It only applies to scenarios, where the
configuration change was triggered by a user generated resize of an
activity (i.e. user drags a corner of an activity and thus changes its
size).
Preserving a window means that we will keep the decor view and non
client decor view around, but remove all children views when the
activity gets destroyed. When the activity gets created again, it will
attach its new content to the preserved view hierarchy. Mind, we
actually recreate application side Window object, since some of its
features might changed, but we retain its elevation (to not trigger
relayout with new layout params).
Preserving the window also means that we don't call the window manager
service to remove and later add the window. Instead, we continue using a
single window state throughout the resize operation.
