Hey, thanks.

There's not much I can do about it at the moment that I know, but I'm open to suggestions from seasoned snippet writers. I added the scale component with the intent to allow you to visualize it quickly if you just want the color output in a few pixels - the script would be a lot faster if it only ran once instead of once per pixel but that would require either:

1) Access to bitmaps from the Prepare() function
2) Buffer a pixel in memory so that it's not re-rendered when it's accessed.

The way it works right now is that even if you're scaling the exact same pixel across multiple other pixels, the original Map function is called every time that happens. Otherwise we could output just four pixels and then scale their final bitmap values for what would be a gigantic increase in performance.

Oh I didn't know about that snippet. That's a clever idea. And it's indeed much faster and opens up room for a lot of improvements in the algorithm.

I'll play around with it and release an update. Thanks!

You done did it! Awesome update!

Yeah, this Image may be helpful to debug the color code. Probably the rectangular
nature that makes it so hard. Random offsets will likely fix this one.
