    gallium: new draw stage for polygon stipple.
    
    For hardware without native polygon stipple.  Create a 32x32 alpha texture
    that encodes the stipple pattern.  Modify the user's fragment program to
    sample the texture (with gl_FragCoord) and kill the fragment according to
    the texel value.
    Temporarily enabled in softpipe driver, replacing the sp_quad_stipple.c step.
