      *         This may be useful to, for example, move the origin in and
      *         over a bit to account for a margin, scale the canvas,
      *         or apply a rotation.  Note1: the SkPDFDevice also applies
      *         a scale+translate transform to move the origin from the
      *         bottom left (PDF default) to the top left.  Note2: drawDevice
      *         (used by layer restore) draws the device after this initial
      *         transform is applied, so the PDF device does an
      *         inverse scale+translate to accommodate the one that SkPDFDevice
      *         always does.
