Ty for not procrastinating as much as I do 🙏

I think this implementation of contain() will have to be modified somehow, because as written, it will produce artifacts.
(I don't think setting wrapping would be a good solution.)
It would be nice if the canvas would show through around the edges...

I'm not sure this is possible. contains() might only be usable with certain images like the one from the example that have a single color at its border.

OK, all is good. I see that contain() can be made to work perfectly if the texture has a transparent background. 👍
