Now GtkWrapBox has "horizontal-spreading" and "vertical-spreading" options, before GtkWrapBox never spread out children across the opposing orientation (i.e. it never grew "lines" larger then their natural width, they would act as if set to GTK_WRAP_BOX_SPREAD_START, now they are completely configurable).
