The libdpx writer strides the caller's pixel buffer by the declared end-of-line padding, but our scanline buffer is always tightly packed. Since the value was passed through from an input file's header, a crafted DPX made the writer read far past the end of the buffer during dpx-to-dpx conversion. Declare zero padding instead; we can never supply a padded buffer, so the pass-through could not have produced a correct file anyway.
