Tristan Van Berkom e976abe825 Split up GtkWrapBox:spreading property into two orientation specific properties.
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).
