Currently, drawing on the map with an object using an icon larger than world.icon_size skips every tile with any amount of pixels overlapping. (If you have a 48x48 icon in a 32x32 world, for example, filling a square with it will only place on every other tile)

I think this should be toggle-able. I understand that if you have some kind of banner-type thing that fills the icon completely, it would make more sense to have it how it is.
