SliverPhysicalParentData class
Parent data structure used by parents of slivers that position their children using absolute coordinates.
For example, used by RenderViewport.
This data structure is optimized for fast painting, at the cost of requiring additional work during layout when the children change their offsets. It is best used by parents that expect to have few children, especially if those children will themselves be very tall relative to the parent.
