Fast drawing image from list
When the builder is done, I draw 43200 colored dots in a blink of an eye. If you click the green flag again you'll see! :-D I also needed to look into and implement the variable to list packer/builder because of problems uploading large lists. I'm storing a full-screen image here, 480x360, this makes the list carry 172800 elements. Way to large for uploading/saving online. I've added some code/comments inside to show how it works. Thanks to @bip901 for optimizing tip! Thanks to @MartinBraendli for testing without clones and make the drawer twice as fast!
