How should BiDi work?

• This table shows all the different combinations of BiDiMode with Horizontal Alignment.
  
  
• The table reflects the behavior of Delphi's VCL controls, and uses Delphi's terminology for BiDiMode settings.
  
  
• The example is given with Hebrew words and punctuation marks, in order to give a realistic demonstration of BiDi behavior. For those interested, the first phrase means "Not good...", the second means "Excellent!", and the third means "Alright;".
