Now works on snap! smoothly!
Fixed things that were causing lag on snap!

Press L for Lag test! (will create 10.000 items!)
When you press it you will hear a sound. Please wait until you hear it again, then you press the green flag!

What is this:
it's a infinite drawing engine that only uses the items that it needs to display the colored tiles!
Even with 10.000 items it's still fast!
How is this possible?
it uses binary search algorithm to find any item in the list faster than just checking the entire list!
When you draw on a tile it uses binary search insertion sort to place the items in the correct position faster!
Binary search works only on sorted lists!
