Object.defineProperty('hitTestBuffer');
| Type | Description | 
|---|---|
| int | The hit test buffer. Default value is 0. | 
The hit test buffer is used to make the test point "bigger" to compensate for errors and provide smoother hit-testing. For example, if the buffer value is 2, a square with sides 4 pixels long will be used around the test point to perform the hit-testing. This can be very useful when the target element is small in size on a touch device.
