Linden Lab already had Win32 and OSX LLWindow implementations with which
it was happy before the SDL implementation came along - there has
never been a clearly positive net gain from switching all platforms to
SDL.  SDL doesn't handle everything we need from an LLWindow
implementation natively, so there would always be platform-specific
pieces (to which SDL is at best orthogonal and at worst somewhat
obstructive).
