Sprite sheets

[maxim-zhao]

On this note, a feature that could have been very useful in the tool, would have been to be able to tell the sizes of the entities in the picture. For example 16x32. It would have then organized the tiles accordingly to put them one after another for every entity.

This would have avoided having to stack, for example, tenths of NPCs vertically in a 16*2048 picture.

An option that picks a sprite size, which is required to be a divisor of the image size, then we process the image into a tall stack based on this before further processing. The tilemap reflects the rearranged image.
