Prepared things for the Windows and Mac OS X backends.
Began the Windows port: wrote the pen code.
Wrote (most of?) the Windows font code.
Wrote the implementation of Image on Windows. There are lots of loose ends to fix here...
Fixed compilation errors and added all sorts of missing crap. Now to figure out why the Windows code panics...
Fixed Windows runtime panics... now to see why it's not working -_-
Fixed some of the Windows problems; added a caveat about Image.Image()'s now-meaningless alpha data.
More Windows text fixes.
