I think it's not used much because most people don't know it's 
available.  These are the (only?) cases where it's useful: you don't 
want to type the dummy, pass-through vertex shader over and over and 
over.  Maybe we should replace it with a more limited "[vertex shader 
passthrough]" option?

I did the refactor in this series mostly to reduce the amount of reading 
in the patches that counted.  I also tried a sed job (via emacs macros), 
but many of the pass-through shaders were very slightly different. :(
