Add opacity from HN dev? #3

@jes An enterprising Hacker added opacity to the cars, as you requested, @ roughly https://news.ycombinator.com/item?id=32947303#32948701 (closest link I could find). Interested in updating repo w/ that?

This works really well on the embedded version in my blog, but sadly the latest "real" version now uses additive blending to get a nicer lighting effect, so drawing a black circle over the top of stuff now does nothing.

We could maybe add a flag that makes it switch to alpha blending for the black circles, and then back to additive blending for the actual lights. I might play with this if the mood strikes me. For now the biggest part I don't like is how clunky the lane changes are.

Came here to post about drawing car bodies this way (with circles or rectangles).

Lamp posts could be done similarly by drawing tall black rectangles.
