The last frame of an animation stays stuck on the screen for a couple of frames.
Specifically, the "Quick Contact" animation that animates the picture
closed (fades/scales it away) animates all the way to the end... then hangs there
briefly before being taken down.
The problem is a rendering bug where we correctly detect that a DisplayList
has nothing to draw (since the last frame is completely transparent, alpha==0),
but incorrectly ignore the fact that we cleared the transparent-background
window prior to not-drawing that DisplayList. When we detect that there's
nothing to draw, we don't bother swapping buffers. So even though we drew
the right thing (clearing the buffer), we didn't actually post the buffer to the
screen.
This change factors in both the clear and the draw to decide when to swap buffers.

The new implementation more accurately tracks the velocity
of flings and takes care to avoid obvious discontinuities.
The main goal is for a fling to appear to be a linear
extension of the movement already in progress. The minimum
fling velocity is set to ensure that flings appear to be
fairly smooth despite being discretized.
Use sequences of repeated key events instead of individual
down/up events to represent continuous motions in one
direction which can be helpful for stopping flings at boundaries
such as when flinging the cursor position within a text view.
Compute the movement thresholds based on the physical
size of the touch pad, if known. If not known, we assume a
nominal size.
Support stopping flings with a tap just like we do for
normal touch events elsewhere in the framework.
Moved the detection of ASSIST swipes into the InputReader
where it belongs. These swipes must be detected globally
to ensure consistent behavior across the all applications.
Added a custom protocol in EventHub to enable input device
drivers to override the timestamp of the following events
in a packet. This change enables input device drivers
that have a better idea of when an input event was actually
generated to pass this information to the input system.
Particularly useful with uinput.

The goal is to better encapsulate this code to make it easier
to maintain and to facilitate some upcoming changes.
Some of the variables have been renamed but the logic is unchanged.

GLSurfaceView will now automatically use the Choreographer to
schedule render updates on VSYNC. This happens only in
RENDERMODE_CONTINUOUSLY.
GLSurfaceView was rewriten to use a Looper and a HandlerThread
instead of a custom thread.
The basic mode of operation is unchanged, however the implementation
is largely different.
Removed support for older GPUs which had a limited number of contexts.

Several conditions can cause an AbsListView's data set observer to be
removed and nulled out. If for some reason the view receives duplicate
onDetachedFromWindow events this could cause AbsListView to attempt to
unregister a null observer. Skip this unregister process if this
happens.

If someone explicitly installs an update to a system-bundled package,
we infer that this means they actually want to use the new code.

Use larger files in tests. Using small files fails because downloads
complete too quickly. Using files that are too large fails because
downloads take too long.

This change adds new APIs to enable applications to generate custom Systrace
begin/end events. Application-generated events use the ATRACE_APP_TAG tag,
which is enabled only if either the application has declared itself debuggable
in its manifest or ro.debuggable is set to 1 on the device.
