Clearly that's not so, since when I take the output of DOTGenerator and 
pass it to dot, the results are very different than those produced 
within ANTLRWorks itself.

And as I wrote earlier, when I capture ANTLRWorks invocations of dot and 
log the arguments its using, the only invocations I see look like this:

This means that ANTLRWorks appears to only be using dot to transform 
one .dot file to another (-Tdot means produce DOT-format output).
