 (8) How would an existing fragment program be ported to use the
    program option ARB_fragment_program_shadow?

       RESOLVED:  Fairly simply, but with a caveat on undefined behavior.

       !!ARBfp1.0
       # A simple example of shadow map (R <= Dt)
       #
       # SHOULD make sure that the 2D texture bound to texture unit 0:
       #    texture format of DEPTH_COMPONENT (for highest quality comparison)
       #    TEXTURE_MAG_FILTER is NEAREST
       #    TEXTURE_MIN_FILTER is NEAREST or NEAREST_MIPMAP_NEAREST
       # Assumes DEPTH_TEXTURE_MODE is LUMINANCE or INTENSITY
       #
       TEMP Result;
       ALIAS Dt = Result;
       TEX Dt, fragment.texcoord[0], texture[0], 2D;
       SGE Result, Dt.x, fragment.texcoord[0].z;      # R <= Dt

       !!ARBfp1.0
       OPTION ARB_fragment_program_shadow;
       # A simple example of shadow map (R<= Dt)
       #
       # MUST make sure that the 2D texture bound to texture unit 0:
       #    texture format of DEPTH_COMPONENT and a
       #    TEXTURE_COMPARE_MODE of COMPARE_R_TO_TEXTURE
       # Otherwise, the Result is undefined.
       #
       # Remember also that to get R <= Dt to set:
       #    TEXTURE_COMPARE_FUNC of LEQUAL
       #
       # A single compare equivalent to the above example will result if:
       #    TEXTURE_MAG_FILTER is NEAREST
       #    TEXTURE_MIN_FILTER is NEAREST or NEAREST_MIPMAP_NEAREST
       # Otherwise, percent closer filtering may be applied.
       #
       TEMP Result;
       TEX Result, fragment.texcoord[0], texture[0], SHADOW2D;
