API REVIEW REQUEST: Public API for Node Orientation

[steve.x.northover at oracle.com]

Hi all,

I have been looking into Node Orientation which is an API that controls 
the directionality of a Node.  This is different from BIDI or the BIDI 
algorithm which governs the direction of text.  Node orientation 
concerns the flow of visual data which is either left-to-right or 
right-to-left.  The best example is a tree control.  In tree control 
that is oriented right-to-left, the expansion arrows point to the right 
and the branches of the tree expand from the right to the left.
