#ifndef _VM_SCREEN_H_
#define _VM_SCREEN_H_
First stab at adding graphics. This involves using glfw. This first commit creates a window but doesn't do anything with it; it also just hangs until you can escape out somehow.

#include <stdbool.h>
Really basic implementation of SDL2. Plus a crappy rectangle to prove that our vm screen code is working in principle. (It will be removed shortly.)

Add ability to set logical size of window at any time We also removed the scale field, as the screen does not expect to manage its own logical coordinates in SDL. Additionally, we added an xcoords and ycoords function to the screen externs so that you don't have to "know" that screen has those as fields.
