This is correct, '+a0.0' will supersample all pixels so it will be
really slow but you will also get good results of course. For better
performance it is often a good idea to use adaptive antialiasing and a
threshold slightly above 0. To avoid persistent artefacts you can try a
fairly strong jitter.
