This is generally called in conjunction with 'gimp_image_undo_thaw' to temporarily disable an image undo stack. This is advantageous because saving undo steps can be time and memory intensive. 'gimp_image_undo_{freeze,thaw}' and 'gimp_image_undo_{disable,enable}' differ in that the former does not free up all undo steps when undo is thawed, so is more suited to interactive in-situ previews. It is important in this case that the image is back to the same state it was frozen in before thawing, else 'undo' behaviour is undefined.",
