Can I reuse uv_unwrapper from/for SF3D?

[YanWenKun]

I once made a Windows Portable Bundle for SF3D, and I noticed that most dependencies of SF3D and SPAR3D are identical.

So I'm wondering if I can put these two into one Python environment, therefore one prebuilt package.

Then I noticed a few differences in method _handle_remaining_uvs of uv_unwrapper/unwrap.py :

I don't really know if they are interchangeable, so my questions are:

1. Is it OK to put SF3D and SPAR3D in one Python environment?

2. Which uv_unwrapper should I use? The SF3D one, or the SPAR3D one?

Thanks in advance!
