I was playing around today and decided to attempt a glow effect. After an hour or so, I got this engine. It is capable of making text, colors, lines, and even gradients glow! Feel free to use it, just give credit. Explanation: What the code does first is set the ghost effect to be nearly transparent. Then it takes a few steps in one direction, stamping after each step. The reason that the glow thins out is that the closer points are hit by more stamps. Say, a point 3 units away might get hit on stamps 3 through 12 (9 points), while a point 20 units away might only receive 20 and 21. After that, it returns to its original position. It then does the same thing but in a slightly different direction. And so on around the circle... You might see this in a upcoming game
