Previously, a Fade transition would only affect a view if its
parent hierarchy was not also affected between the start/end states.
This caused problems for views which were removed from their parents
between scenes when their parents' visibility also changed between those
scenes. The effect would be that the transition would fade the parent...
but the child would no longer be in that parent, so the user would just see the
child view blink out.
This fix ensure that views are faded appropriately by fading them
regardless the parent hierarchy; if a view is removed from its
parent, fade it out.
Additionally, if that view has not been removed from its parent, but
its parent is no longer parented *and* scene being
transitioned from is based on a layout resource file (and thus
the views are considered temporary after transitioning), then it is
removed from its parent to be faded out in the overlay.
Also, renamed TextChange to ChangeText to be more consistent with
other transition class names.

It would be useful for a transition to declare not just which
targets it wants to be run on, but also which targets it wants
to avoid. For example, you may not want to animate the items of
a ListView, or some other specific target in the view hierarchy.
This change adds various exclude*() methods which make it
possible to alter a transition to automatically ignore specific
views, ids, or classes in the hierarchy.

Path ops can be used to combine two paths instances in a single path
object. The following operations can be used:
- Difference
- Reverse difference
- Union
- XOR
- Intersection
To use the API:
Path p1 = createCircle();
Path p2 = createRect();
Path result = new Path();
result.op(p1, p2, Path.Op.DIFFERENCE);
This code will subtract the rectangle from the circle and generate
the resulting path in "result."

Some view changes require more flexible transitions than the
defaults provided by Crossfade and TextChange - this change supplies some
of that flexibility.
Also, starting a new transition on a hierarchy undergoing a transition
caused the first to get canceled, then the start values to be retrieved.
The new transition should actually get the start values from the intermediate
state of the views, so we now cancel the previous transition only after the
start values have been captured.

Transitions used to be three phase:
- captureValues(): get all relevant property values in the
affected view targets
- setup(): set appropriate start values for affected views
prior to any transitions being played
- play(): create/play Animators for affected views
Now the second and third phases have been collapsed (and named
"play()"). This single step sets initial values for target views
and creates any Animators that should be played during the transition.
The transition mechanism stores these Animators and then starts
them at the appropriate time in the overall transition.

Previously, Fade transitions did not work correctly on hirearchies; they
only handled individual views. in particular, they would side-effect all
fading views by removing them from their parent to fade them out in the
overlay of the scene root. This worked for the fade-out transition itself,
but caused problems when those same hierarchies were added back in and
another Fade was run on the hierarchy, because now all of the views inside
that parent node had been removed, so they didn't fade in at all.
The fix was to add logic in Visibility to detect when a disappearing
view was inside a hierarchy that was also disappearing, and to skip the
fade on the views inside that hierarchy, leaving only the top-most
disappearing view to be faded out, thus preserving the hierarchy under
that faded-out group.
Along the way, there were various cleanups, fixes, and refactorings in the
transition code, and slight API modifications.

Also a few little tweaks to the ArrayMap implementation. Note that
these are fairly parallel implementations; I looked at what I could
abstract out as a base class, but there isn't really all that much without
making the resulting code more general and thus slower. If we kept
the data structure for ArraySet the same as map, where the array has
two values per entry, then they could probably share a lot of code.
I couldn't really bring myself to do that at this point, though...

setDuration() wasn't handled correctly for TransitionGroup; it should
propagate the value to its children.
Also, videos with no ids were not being handled correctly. The transition code was
using the default id on those views (-1) to store start/end data about the view,
causing multiple non-id views to clobber values in the hashmaps. The correct approach
should be to ignore default id values - only store information about the view
instances, not about the unset ids.
Also, added a new test InterruptTest to be used to fix the current behavior of
not handling situations where new transitions start while old ones are still taking place.

This is a new kind of key/value mapping that stores its data
as an array, so it doesn't need to create an extra Entry object
for every mapping placed in to it. It is also optimized to reduce
memory overhead in other ways, by keeping the base object small,
being fairly aggressive about keeping the array data structures
small, etc.
There are some unit and performance tests dropped in to some
random places; they will need to be put somewhere else once I
decided what we are going to do with this for the next release
(for example if we make it public the unit tests should go in
to CTS).
Switch IntentResolver to using ArrayMap instead of HashMap.
Also get rid of a bunch of duplicate implementations of binarySearch,
and add an optimization to the various sparse arrays where you can
supply an explicit 0 capacity to prevent it from doing an initial
array allocation; use this new optimization in a few places where it
makes sense.

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.

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.
