Ok I just pushed in a new and slightly changed api:

gtk_wrap_box_insert_child_with_padding (GtkWrapBox  *layout,
                                        GtkWidget   *widget,
                                        gint         index,
                                        guint        horizontal_padding,
                                        guint        vertical_padding,
				        GtkWrapBoxPacking packing);

I collapsed both the horizontal and vertical expand/fill options into
a single enumeration:

 * GtkWrapBoxPacking:
 * @GTK_WRAP_BOX_H_EXPAND: Whether the child expands horizontally.
 * @GTK_WRAP_BOX_H_FILL:   Whether the child fills its allocated
horizontal space.
 * @GTK_WRAP_BOX_V_EXPAND: Whether the child expands vertically.
 * @GTK_WRAP_BOX_V_FILL:   Whether the child fills its allocated
vertical space.
 * Specifies how widgets will expand/fill vertically and
 * horizontally when placed inside a #GtkWrapBox.
typedef enum
  GTK_WRAP_BOX_H_FILL   = 1 << 1,
  GTK_WRAP_BOX_V_FILL   = 1 << 3
} GtkWrapBoxPacking;

I also took care of renaming SPREAD_BEGIN --> SPREAD_START
and named the padding options "horizontal-padding"/"vertical-padding"
to be more consistent with the rest of the wrap-box api (generally
I think those are more readable than "xpad"/"ypad").

There should be no more trailing whitespace in gtkwrapbox.h as well...

Thoughts anyone ? its still early enough I can come back and change
some details...
