Tests that there is an upper limit on the number of hit rects generated per layer. http://crbug.com/299177.
Test node has 99 children with 100 rects
Test node has 100 children with 101 rects
FAIL - got 101 rects, expected 1.
Test node has 101 children with 102 rects
FAIL - got 102 rects, expected 1.
