/*
	OpenGLWindow.h
	Implementation of a window with OpenGL context. Not really OpenGL specific, other than in creation of GraphicsContext.
	Bulk of creation can be used in any api/context (glfw compatible with Cocoa, X11, or Windows). Based entirely upon the 
	work of @TheCherno in his game engine series.
