Shows the maximum number of possible clones at a given point in time on the stage. Found them to be 301 on 20180307 Adding a 2nd object and running it again, seems to keep going up to 301, so it must be a max number of clones either per object or for any object (haven't tried to see which one is the case, can try adding clones to a 2nd object too), but adding more objects by hand (that is increasing the total number of objects), doesn't seem to cause any decrease in the number of clones you can create. UPDATE: the clone limit is documented at https://en.scratch-wiki.info/wiki/Cloning
