I'd put the blinky stuff into the same tool and make it be an option.
For what it is worth, I generally don't like blinky stuff but I included
it in the graphical diff that is in the gerbv testsuite and also the pcb
testsuite. I find it much easier to spot that tiny difference between
two complicated images. So as far as I'm concerned, this is one of the
few times where blinky is good.
