Added ability to define colors at UV coordinates along a path #4353

murl-digital · 2024-04-12T23:00:06Z

I had to make a couple types not Copy because closures, but it should'nt be a massive deal.

I tried my best to make the API change as non breaking as possible. Anywhere a PathStroke is used, you can just use a normal Stroke instead. As mentioned above, the bezier paths couldn't be copy anymore, but IMO that's a minor caveat.

This looks very promising! ColorMode has the potential to be useful for more things in the future too, like the fill color for shapes (not in this PR though!)

While playing around with trying to remove the 'static lifetime bound when making a new ColorMode, I found that adding a lifetime bound to the type as a whole seemed to work, however the change bubbles out to all of egui very quickly, and would very much be a breaking change. I think this is something that should be looked into further
