Point tessellation is similar to line special case, except that we
only tessellate one point (as a circle or rect) and duplicate it
across other instances.
Additionally:
Fixes square caps for AA=false lines
Cleanup in CanvasCompare, disabling interpolation on zoomed-in
comparison view

When the Android runtime starts, the system preloads a series of assets
in the Zygote process. These assets are shared across all processes.
Unfortunately, each one of these assets is later uploaded in its own
OpenGL texture, once per process. This wastes memory and generates
unnecessary OpenGL state changes.
This CL introduces an asset server that provides an atlas to all processes.
Note: bitmaps used by skia shaders are *not* sampled from the atlas.
It's an uncommon use case and would require extra texture transforms
in the GL shaders.
WHAT IS THE ASSETS ATLAS
The "assets atlas" is a single, shareable graphic buffer that contains
all the system's preloaded bitmap drawables (this includes 9-patches.)
The atlas is made of two distinct objects: the graphic buffer that
contains the actual pixels and the map which indicates where each
preloaded bitmap can be found in the atlas (essentially a pair of
x and y coordinates.)
HOW IS THE ASSETS ATLAS GENERATED
Because we need to support a wide variety of devices and because it
is easy to change the list of preloaded drawables, the atlas is
generated at runtime, during the startup phase of the system process.
There are several steps that lead to the atlas generation:
1. If the device is booting for the first time, or if the device was
updated, we need to find the best atlas configuration. To do so,
the atlas service tries a number of width, height and algorithm
variations that allows us to pack as many assets as possible while
using as little memory as possible. Once a best configuration is found,
it gets written to disk in /data/system/framework_atlas
2. Given a best configuration (algorithm variant, dimensions and
number of bitmaps that can be packed in the atlas), the atlas service
packs all the preloaded bitmaps into a single graphic buffer object.
3. The packing is done using Skia in a temporary native bitmap. The
Skia bitmap is then copied into the graphic buffer using OpenGL ES
to benefit from texture swizzling.
HOW PROCESSES USE THE ATLAS
Whenever a process' hardware renderer initializes its EGL context,
it queries the atlas service for the graphic buffer and the map.
It is important to remember that both the context and the map will
be valid for the lifetime of the hardware renderer (if the system
process goes down, all apps get killed as well.)
Every time the hardware renderer needs to render a bitmap, it first
checks whether the bitmap can be found in the assets atlas. When
the bitmap is part of the atlas, texture coordinates are remapped
appropriately before rendering.

erroneous inclusion of R file for test files is causing build breakage
on the server. Remove the offending lines.

This checkin has preliminary API (in flux, definitely changes still
to be made) and implementation for a new "Scenes & Transitions" feature.
The current implementation allows you to define different Scenes
(via layout resource IDs or callbacks) and Transitions to be used when
changing to those scenes. By default, scene changes will use AutoTransition,
which generally does the right thing.
There are no overview docs or tutorials yet. The best way to learn how things
work is to see the code for the various tests in
frameworks/base/tests/TransitionTests.
Expect the API to change. Expect the implementation to change (mostly to add
more functionality). Expect bugs, but tell me if things do not work
as expected.

CanvasCompare will output a JSON file with test results, and can take
such files as input for baseline comparison. The new logcat output
breaks down results into per-test and per-modifier improvement and
regressions.

If an app from the apk cannot be launched then skip it in compatibility
test, rather than generate a null pointer exception.

This is the best and only way for apps to listen for
notifications: create a NotificationListenerService, wait
for the NoMan to bind to you (as a result of the user
checking a box somewhere in Settings and agreeing to a
scary dialog box), and you'll start receiving notification
posted and dismissed callbacks. Your service, while enabled,
will also be able to clear one or all notifications.
Use this power wisely.
This change moves StatusBarNotification out of
com.android.internal into android.service.notification.
[Internal customers, including System UI and early users of
the system-only listener binder API, will need to be
updated.]

This optional parameter ensures that, before test starts, device
has the listed account types configured already.
e.g. to test app launch time of Gmail, a valid Google account
must present on device

This change will greatly simplify the multi-threading of all
shape types.
This change also uses PathTessellator to render convex paths.

new approach:
* for each app
* initial launch
* sleep 7.5s
* do 10 iterations: launch app with force stop + sleep in between
* report average of 10 launches
