That's not the same library but the exact same implementation. 
The one I'm using (https://github.com/d-gamedev-team/dimgui) 
borrows its from the deimos bindings.

So since the a struct cannot inherit from a class and vice versa, 
then the entire approach taken by the library must be 
reconsidered going forward. A little over my head at this point.

Thanks for the assist.
