Some things (like handling offsets for ordinary texturing) shouldn't be
too difficult (though make things slower) - might need to plumb it
through 100 functions however. Explicit derivatives for ordinary
textures ought to be pretty easy too (in any case the method used to
calculate lambda in softpipe isn't terribly accurate), though they are
indeed a major pita for cube maps...
