reorderItems
Reorder items from logical order to visual order.
The visual order is determined from the associated directional levels of the items. The original list is unmodified.
(Please open a bug if you use this function. It is not a particularly convenient interface, and the code is duplicated elsewhere in Pango for that reason.)
Return
a GList of PangoItem structures in visual order.
Parameters
items
a GList of PangoItem in logical order.
