Detailed Description

The bidirectional state class. This class contains functions that implement the Unicode Bidirectional Algorithm, which changes text from logical order to display order for the correct display of right-to-left scripts, like Arabic and Hebrew. A TBidirectionalState object carries the embedding level and stack from one line to the next. On construction it is in its 'start of paragraph' state.
