vid.aspect is removed (for now) as it was not really the right idea (I
really didn't know what I was doing at the time). Nicely, this *almost*
fixes the fov bug on fresh installs: the view is now properly
upside-down rather than just flipped vertically (ie, it's now rotated
180 degrees).
Many surfaces are missing (I suspect it's due to transform stage
management in the index emitter), and currently only the light maps are
rendered (still not binding the correct textures), but the basics are
working.
