It's okay that it's a prime number, because I can make the grid just extend a little past the bottom.  It doesn't need to fit an exact measurement, since this is just a sandbox kind of plotter.  There will just be a tiny amount of computational waste, but that's okay if it means we get crisper lines where we want them.
