I'd like to be able to choose how big a grid square equates to in the final image. e.g. rather than saying my final image is 128x128 pixels, I'd rather say that I'd like each square in my model to export to 8x8 pixels in the final image, and the image size will then be dependent on the size of the model (i.e. "x" number of tiles * "y" number of pixels per tile).
