class TBidiLogicalToVisual
/** 
This class is a low-level class for bi-directionally reordering text. It 
allows the re-ordering of text using no leaving functions at all, and provides 
a finer degree of control than TBidiText. However, it should not be used 
without understanding the basics of the Unicode Bi-directional Reordering 
Algorithm.
