public virtual int HitTestBuffer {get; set;}
get_HitTestBuffer();
set_HitTestBuffer(value);
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 a length of 4 pixels around the test point will be used to perform the hit-testing.
