-// As the grid is resized, its images fill the requested space:
-// - corner images are not scaled
-// - top and bottom images are scaled horizontally
-// - left and right images are scaled vertically
-// - the center image is scaled in both directions
-//
-// If one of the non-center images is smaller than the largest images in its
