Comment 31 for bug 92296

Jeff, is it possible then to fix bug #11421 by using the same code, or at least the same approach?

btw, there are some documents that are crashing now in this assert() in CairoOutputDev::drawImageMaskPrescaled():

if (n != 0) {
       printf("n = %d (%d %d %d)\n", n, head_pad_size, pix_size, tail_pad_size);
      assert(n == 0);
}

like the one reported here:
