           Summary: On some XP machines SDL_INIT_VIDEO fails unless using
                    windib so we should have some method of falling back
                    to windib even if we've tried directx

set SDL_VIDEODRIVER=windib
is the only way to make ioquake3 work by default on some (windows xp) boxes,
I'm still not sure WHY this happens or how a machine gets broken to the point
where this happens. But...

I understand that ioquake3 currently tries forcing windib at SDL_INIT_VIDEO
time if in_mouse = -1 or directx if in_mouse isn't -1.

However we should unset the variable if SDL_Init() fails and try again, and
pray it works at all, no matter how the mouse responds

If you don't use that on this machine you get...:
