    softpipe: Take all lods into account when texture sampling.
    
    This patch churns a lot because it needs to change 4-wide filters into
    single pixel filters, since each fragment may use a different filter.
    
    The only case not entirely supported is the anisotropic filtering.
    Not sure what we want to do there, since a full quad is required by
    that filter.
