dxcore.dll or dxgi?

[James McDonnell]

Hi-d ho winerinos,

I have made some changes to add a dxcore.dll on a personal branch. I 
want to upstream the changes, however I'm unsure of whether I should 
create a new dll or just append it to dxgi.

Dxcore overlaps with dxgi, but presumably has separate functionality as 
well.

Thoughts?

Here is my branch if anyone wanted to review the commits.

Cheers,
