1. Views are represented as AccessibilityNodeInfos to AccessibilityServices.
2. An accessibility service receives AccessibilityEvents and can ask
for its source and gets an AccessibilityNodeInfo which can be used
to get its parent and children infos and so on.
3. AccessibilityNodeInfo contains some attributes and actions that
can be performed on the source.
4. AccessibilityService can request the system to preform an action
on the source of an AccessibilityNodeInfo.
5. ViewAncestor provides an interaction connection to the
AccessibiltyManagerService and an accessibility service uses
its connection to the latter to interact with screen content.
6. AccessibilityService can interact ONLY with the focused window
and all calls are routed through the AccessibilityManagerService
which imposes security.
7. Hidden APIs on AccessibilityService can find AccessibilityNodeInfos
based on some criteria. These API go through the AccessibilityManagerServcie
for security check.
8. Some actions are hidden and are exposes only to eng builds for UI testing.

even in portrait mode.
Note: requires a definitive selectAll icon from designers.

This is the type returned by event.getX/Y methods. Conversion
to ints is only performed when needed. Low performance impact
since there is only a minimal amount of computations on these
values.

* commit '7dfdb914206eafbf2aa4533e9b6a50428a5d0d3d':
Change measurement of effective screen height for PopupWindow now that DisplayMetrics reports it without system decorations.
This is needed for specific TextEdit (such as AutoCompleteTextField)
which do not want to display the "No suggestions available" message.
