SliverGridLayout class

The size and position of all the tiles in a RenderSliverGrid.

Rather that providing a grid with a SliverGridLayout directly, you instead provide the grid a SliverGridDelegate, which can compute a SliverGridLayout given the current SliverConstraints.

The tiles can be placed arbitrarily, but it is more efficient to place tiles in roughly in order by scroll offset because grids reify a contiguous sequence of children.
