Display.h

/*
Display Class
This is a wrapper object that contains both a Window and a Renderer, 
when creating graphics you should just need one of these to do all 
the jobs you need.

This handles anything renderable including Interactables and text

This also supports z-ordering! The larger the number the further
forward it is.
