How to center the master window in screen?

Just one simple question, is there an existing way to center the master window in screen?

If the answer is no, I may need to tweak the shiny/driver layer to archive it.

I'm digging GUI framework for go recently. From imgui->imgui-go->nuklear->golang-ui/nuklear all the way down to nucular. I think I just found the one I'm looking for!

Thanks for your effort. It's a really good job!
