Cell swizzle order that this layout applies when converting cell positions to local space.
Swizzling reorders the cell axes. The default GridLayout.CellSwizzle.XYZ keeps cell X, Y, and Z mapped to local X, Y, and Z. GridLayout.CellSwizzle.XZY swaps the Y and Z axes, which is useful for placing a 2D grid on the XZ ground plane of a 3D scene. See CellSwizzle for all available orders.
