rBda95fa834444: Fix UV unwrap not working with only one pinned vertex

Summary

This commit fixes T79590 UV Island Won't Unwrap If Only One Vertex Is Pinned

When unwrapping UV island with only one pinned vertex, it will unwrap as if there's no pin, and then translate the whole island to keep pinned vertex position unchanged.

Pin only one vertex

Select all and unwrap

Thanks for the patch. I think the solution should be a bit different The automatically found pins are not necessarily good candidates for pinning along with any other vertex.

Instead I think it can still pick 2 pins automatically, but then after unwrapping translate the entire UV chart so that the pinned UV remains in place.

This revision now requires changes to proceed.Aug 6 2020, 4:53 PM
