Drawing with alpha - avoid overlapping effect?

[ggschelling]

@dehli I have another question about drawing with transparent colors. As you can see, your line segments are overlapping each other and you get this effect. Maybe you already implemented a way to avoid this? Or, if not, maybe it's something you want to consider as an update feature. Maybe you could draw the line onTouchUp event as one and delete the preview segments, which is drawn as you still move your finger across the screen.

Hi, I'll investigate this! Thanks.

Edit: It wasn't as easy of a solution as I had initially thought. If somebody else wants to tackle this, PRs are welcome. I might attempt it again at some point :)
