9Introduction
10------------
11
12A Scene is an encapsulation of the state of a view hierarchy,
13including the views in that hierarchy and the various values
14(layout-related and otherwise) that those views have. A scene can be
15defined by a layout hierarchy directly or by code which sets up the
16scene dynamically as it is entered.
17
18A Transition is a mechanism to automatically animate changes that
19occur when a new scene is entered. Some transition capabilities are
20automatic. That is, entering a scene may cause animations to run which
21fade out views that go away, changeBounds and resize existing views
22that change, and fade in views that become visible. There are
23additional transitions that can animate other attributes, such as
24color changes, and which can optionally be specified to take place
25during particular scene changes. Finally, developers can define their
26own Transition subclasses which monitor particular property changes
27and which run custom animations when those properties change values.
28
29TransitionManager is used to specify custom transitions for particular
30scene changes, and to cause scene changes with specific transitions to
31take place.
