// Each Control in a Grid has associated "expansion" and "alignment" values in both the X and Y direction.
// Expansion determines whether all cells in the same row/column are given whatever space is left over after figuring how big the rest of the Grid should be.
// Alignment determines the position of a Control relative to its cell after computing the above.
// The special alignment Fill can be used to grow a Control to fit its cell.
// Note that expansion and alignment are independent variables.
// For more information on expansion and alignment, read https://developer.gnome.org/gtk3/unstable/ch28s02.html.
