The file is just an irritant to me. It's outdated HTML, explains
way too much, and it's ugly. I've deleted it and replaced it with
a much shorter blurb in the readme regarding how to play.
At first I was going to just not bother with the resizing thing, but
then I found out that SDL actually has a scaling function built-in.
So rather than depending on SDL_gfx for this one purpose that never
sees the light of day in practice, I have handed that job over to
that function.
