/**
* This test is to verify that touch events bubbles up to the right handler. We emulate couple
* of different gestures on top of the application reflecting following layout:
*
* +---------------------------------------------------------------------------------------+
* | |
* | +----------------------------------------------------------------------------------+ |
* | | +-------------+ +----------------+ | |
* | | | +---+ | | | | |
* | | | | A | | | | | |
* | | | +---+ | | C | | |
* | | | {B} | | | | |
* | | | | {D} | | | |
* | | +-------------+ +----------------+ | |
* | | | |
* | | | |

* | | | |
* | | | |
* | | {E} | |
* | | | |
* | | | |
* | +----------------------------------------------------------------------------------+ |
* +---------------------------------------------------------------------------------------+
*
* Then in each test case we eiter tap the center of a particular view (from A to E) or we start
* a gesture in one view and end it with another.
* View with names in brackets (e.g. {D}) have touch handlers set whereas all other views are not
* declared to handler touch events.
