Performs hit-testing on this AnnContainer at the specified rectangle.
public AnnObject hitTestRect(LeadRectD rect)
The rectangle to be tested in annotation units (1/720 of an inch).
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 testPoint will be used to perform the hit-testing.
If more than one object overlaps underneath the test point, the method will return the object on top of the Z-order.
The HitTestBehavior property determines whether any part or the entire object must be contained inside the rect to be considered hit-tested. if the value is AnnHitTestBehavior.Contains, then the entire object must be contained inside the rect to be considered hit-tested. If the value is AnnHitTestBehavior.Intersects, then if any part of the object can be contained inside the rect it is considered to be hit-tested.
