Don't create a window when testing
...
We do this by creating the notion of a "headless" mode, and skip window
creation in SDL.

Hello world, in rendered text; use nearest pixel sampling
...
The scale change removes some blurriness that we saw when copying pixels
from the bitmap font into the renderer.

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.

Use SDL's render logical size feature
...
This allows us to work with the pure x/y coordinate system we set when
creating the vm_screen. SDL will take care of the translation of those
coordinates to whatever the window size is.

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.)

Actually show a window.
...
This is also the beginning outline of how we want to abstract graphics
away in erc.

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.
