    r300: Writing to result.depth in fragment programs (R3xx; only stub for R5xx)
    
    Setup fg_depth_src for depth writing programs and change early Z (ztop)
    semantics.
    
    Piglit's version of glean/fragprog test passes now (unlike Glean, its
    dependency on EXT_fog_coord, which we don't support, is optional).
    
    R3xx only at the moment, but should be straightforward to adapt to R5xx
    (I don't own an R5xx, and I don't want to break anything.)
