***NOTE: this was originally written for Scratch 2, and the changes to the way the timer block works in Scratch 3 means the 'triangles-per-second' is no longer accurate, so you can't trust what it shows... :( ===================================== Decided it was time I took a look at @Jamohyperturbopro's really neat triangle fill algorithm and see if I could optimise it a bit. This is what I came up with - it's a bit faster than before (and corrects a small bug that happened for isosceles triangles). See comments inside for info about how it works. This project is a remix of his speed test, but here's his original filler: http://scratch.mit.edu/projects/10119728/
