We still use SDL_Rect internally, but we want to abstract the use of it

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.

...
The idea here is to eventually write something that can convert these
(very simple to edit) grid files into an image file which we can then
read parts from and copy onto the screen.
This is also a template for how we can implement other default typefaces
that may come with other platforms we may wish to emulate (for example,
C64).

This allows us to work with the pure x/y coordinate system we set when
