Hahaha! What do you want to bet it probably works /slightly/ different than
either results from no anti-aliasing on brush, or the how the Pencil tool
smh. ;) Obviously we have some things to decide. I still recommend adding
the no anti-aliasing option to the brush though, to use to test agains
these other methods.
