Doris Liu adb8921453 Clean up calls to Rect.intersect()
This CL checks for the return value for Rect.intersect() for whether
there is actually an intersection before taking the return intersected
rect. In the case of no intersection (Rect.intersect() returns false),
an empty rect will be used as the intersection.
