    draw: fix flat shading and screen-space linear interpolation in clipper

    This includes:
    - picking up correctly which attributes are flatshaded and which are
      noperspective

    - copying the flatshaded attributes when needed, including the
      non-built-in ones

    - correctly interpolating the noperspective attributes in screen-space
      instead than in a 3d-correct fashion.
