Gets or sets the threshold buffer value for hit testing.
The threshold buffer value for hit testing, in pixels. The default value is 37.5. Must be a value greater than or equal to 0.
The value of HitTestBuffer can be used to make the test point "bigger" to compensate for errors and provide smoother hit-testing. For example, if buffer is 2, a square with a length of 4 units around test point will be used to perform the hit-testing.
