On this specific point I would recommend as part of the BiDi 
implementation expanding the choices for basic alignment to include a 
new value that means "automatically decide based on bd setting". Then, 
the logic would be to look at the BiDiMode to determine the alignment.

This way all existing code should work as it always has. If a developer 
wanted to adapt his program to take BiDi into account he could just set 
the BiDiMode and change all the alignments that should respond to the 
new alignment value. Any controls that should not adapt can continue to 
set their own alignment independent of the BiDi mode.
