6a230341e1 Make vm_area_set be an inline function. 
Gets most of the benefits of being a macro, but also gains type safety
(which macros do not have).

27f91ec00f Use vm_area with bitfont_offset 
This should further standardize on vm_area.

efb8f04555 Use vm_area for draw_rect. 
This simplifies and to some degree normalizes the way we reference areas
in the vm subsystem.

c7b830bb4a Switch references from SDL_Rect to vm_area 
We still use SDL_Rect internally, but we want to abstract the use of it
in our API. The only thing the rest of the app should care about is the
vm_area struct.

b1c146c62d 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.

4ef9e50792 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.)

8beb761535 Actually show a window. 
This is also the beginning outline of how we want to abstract graphics
away in erc.

b646bfc511 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.
