Subject:  * Use Fede In/Out animation if one of opening/closing apps is in
 compatibility mode.  * preserve compatibility window flag when the app
 updates window's layout params.  * Added assertion in
 DEFAULT_COMPATIBILITY_INFO object to prevent unintentional modification.  * A
 few minor updates     * log/dump message improvement     * Removed
 unnecessary method in FadeInOutAnimator     * Fixed 100 char issue in
 WindwoManagerServer.java
