Simple rectangle filler, not super fast, not super slow, not laggy, not to many blocks, easy to use. If using, backpack the literal only sprite or the define block and give credit to me. HOW TO USE: The myblock is all the code needs, really. The first to inputs are a corner, top left, and the next 2 are just the opposite corner x and y. The rectangle filler myblock itself only has 49 blocks, but the whole project has 64.
