Getting window position on startup

[MixmasterFresh]

I'm trying to implement a custom window drag bar(I'm using decorations: false in window settings), and I think I don't have the information necessary to do it without something a little hacky. Here's where I'm at:

1. the Move action for windows takes an absolute position of where to place it on the screen
2. It seems like if I use the position: position::Centered then there is no way for me to get the starting coordinates of the window for which I could apply offsets
3. I could force the window position to a particular starting location(using position::Specific) and use that to create offsets from, but I'd probably have to use (0,0) to be safe for all devices, which is technically fine(but I don't like it)

Am I right here? Is there any way I can get direct access to the winit window object? Or would it be better for me to submit a PR to add something like a MoveBy that takes a logical offset instead of an absolute position? Or is there a way I can do this without a library code change?

Thanks a ton in advance

This particular use case (custom window drag bar) is one that we haven't considered yet.

If we want to tackle it, I believe we will need to get any new features through the RFC process to precisely state what use cases are we tackling (i.e. the scope) and iterate on the best design for a solution.
