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.

In which I spent an evening plotting a bitmap font
...
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).

Get our test suite working with SDL
...
Had to remove a couple of screen tests for now; it needs a big re-think
now that we're using SDL. Namely, how do we test SDL?

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.

principle. (It will be removed shortly.)

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.

We missed the size multiplier for memset()
...
In doing so, only a small portion of memory would have reliably been set
to zero; specifically, just the first element!
This change should resolve some intermittent test failures to guarantee
that all memory be zeroed.
