|
| +This test passes if the container's scrolling contents layer (the first child of the GraphicsLayer with 4 children)
|
| +draws content only on iterations 1 and 2, and its scrolling block selection layer (the child of the scrolling
|
| +contents layer) draws content only on iteration 3. The scrolling block selection layer should also be much smaller
|
| +than the scrolling contents layer.
