The new display list properties introduces in JB were causing numerous
and expensive memory allocations while scrolling lists. During a scroll
ListView sometimes attempts to apply an offset to views before they are
drawn for the first time. This had the side effect of generating a new
IllegalStateException and its entire stack trace. The exception was
caught inside the display list and never seen by users.
Generating an exception is very expensive both in terms of allocated
memory and CPU time spent crawling the stack.
List scrolls/flings are a common case of this issue but it also happens
during various types of animations. A simple alpha animation, for instance,
can cause the problem to occur.
Another side effect of this issue is more frequent and longer GC pauses.

Allow applications to set a requested volume level on RouteInfo
objects. If requested for a user route, the app-supplied callback will
be invoked to perform actual volume adjustment.

Transition animations were set to fillAfter=false which caused them
to revert when they had completed. Normally this would not have
mattered as the final state was obscured by the new Activity. In
the case of the Phone app the Activities churn so much that the
original Activity was exposed.
Fixes bug 6691421.

Extend MediaRouter.UserRouteInfo to enable setting playback
information, which includes volume. When the user route instance
has a RemoteControlClient, forward any playback information to it.
Enable specifying a callback to be notified of volume events
on the route.
Extend MediaRouter.RouteInfo to enable retrieving playback
information.
Update RemoteControlClient javadoc to reflect which parts of the
API are not intended to be made public.

This fixes a bug where the dots weren't aligned with the center of the view.
The matrix should not contain the offset of the image itself since we really
want to scale about the abstract points. The code now subtracts the image
centering positions (cx,cy) from the point to be scaled.

This change shows how much time is spent updating and executing
framework display lists within a frame.
This change also fixes a crash that happnes if you attempt to
perform a dumpsys gfxinfo while the app is drawing (we are telling
developers to use this new tool.)
