decrease minimum grid size
i think, it would be nice if the minimum grid size could be set to values smaller than 3mm.
I really like the high contrast that comes from half/toning of "rasterizing" the image and i would like to apply this also in application, where the "poster" is viewed from such a small distance that 3mm grid size is simply to small.
thanks in advance, if you could make this possible. Also, if the code was free or i could help contributing this, i would be flattered.
