Terrain tool support for multiple tile sizes

Cheers, Thorbjørn. Agreed after a second look, it’s certainly a massive effort and there are inevitably stacks of higher priorities, smaller tasks for bigger gain. As for the RPG Maker tileset request (issue #1022). I’m not sure I’d use it. The RPG Maker tilesets are confusing at first glance, and even though the micro tiles should save precious texture atlas space, in practice there seems to be enormous amounts of duplicated graphics per animating tile requirements (many artists don’t animate each tile, hence the proliferation of exact duplicates). But more importantly, if I understand correctly the native tilesize would need to be 32x32 such that the micro size is 16x16; but my atlases predominantly 16x16, that format would be out of the question. Thanks again for taking such a thorough look at this!
