This is wrong.  The rect is in the content space of the layer, so the quads do
not need to be transformed.

 
         EXPECT_TRUE(rect.contains(quadRect)) << quadString << i;
         EXPECT_TRUE(remaining.contains(quadRect)) << quadString << i;
         remaining.subtract(cc::Region(quadRect));
     }
 
     EXPECT_TRUE(remaining.isEmpty());
 }
 
 }  // namespace LayerTestCommon
