Raylib looks promising. I installed it along with your Raylib-d. 
I managed to build the example you provided with dub, but trying 
to use it in it's own dub project in a separate directory isn't 
working. Just copying and pasting `app.d` from the very example 
you provided results in a huge wall of errors, mostly "undefined 
reference to [some function]".
