list horizontaly. This supposes that the list is packed into a
scrolled window or something similar, and adjustments are well
set. Step and page increment are those from the horizontal adjustment
of list. Backward means to the left, and forward to the
right. Out of bounds values are truncated.
scroll.type may be any valid GtkScrollType. If scroll.type is
GTK_SCROLL_NONE, nothing is done. If it's GTK_SCROLL_JUMP, the list
scrolls to the ratio position: 0 is full left, 1 is full right.
WARNING: gtk_list_scroll_horizontal is deprecated and should not be used in newly-written code.
