In the case of barchart, what would be the justification for not  
ordering the bars (in a group) as for the key, or vice versa?  Please  
forgive my ignorance - I am curious to understand the design  
principles.  I am certainly very pleased to have the power of  
auto.key in lattice - it's the main reason why I stopped using the  
default plot function.
