Title: Order in which items will be rendered 

Adding a configuration option to determine the order of rendering the items.

Options include Left-to-Right | Right-to-Left | Shortest column first (existing default).

A new enum has been defined for ItemRenderDirection with 3 values:
kItemRenderDirectionShortestFirst, kItemRenderDirectionLTR, kItemRenderDirectionRTL
