Very cool, some more in depth comments?

Hey!

Super cool project, works flawlessly.

If you're around, can you spare a moment to explain how you do the texture mixing? I can probably recover it from the code, but it's probably easy for you to point out the key steps for the effect.

My current guess is using an image texture and modifying the image with PNMImage, then it's just position, getting various values from a 'paint material' texture, scaling with the brush as weight, factoring in some offsets and scaling. Is it done pixel by pixel because that seems like a lot of operations? That's what .store does isn't it?
