Performance

1000 shadow images only need 29MB and 1.01s

In this condition, maximum cpu occupancy rates is 45% and 60FPS when the count of cell is 1000 and quick slide，use iPhone 7, iOS13.3.1.

In extreme cases，no reuse, maximum cpu occupancy rates is 140% and 60FPS when the count of cell is 1000 and quick slide.
