    function 

    @PanicsAtCaller Public Function GridNeighbors(width: Int, height: Int, cell: Vec2i, diagonal: Bool = False): Vec2i[]

    The cells next to cell on a grid of width by height, those on it only: the four along the axes, right, down, left, and up, then, when diagonal, the four corners. A negative size, or a cell off the grid, panics.

    Examples

    Expect(GridNeighbors(3, 3, Vec2i(0, 0)) == [Vec2i(1, 0), Vec2i(0, 1)])
Expect(GridNeighbors(3, 3, Vec2i(1, 1), True).Count == 8)
