-       /* Set the "orientation" key associated with this image. libtiff 
-          orientation handling is odd, so further processing is required
-          by higher-level functions based on this tag. If the embedded
-          orientation tag is 1-4, libtiff flips/mirrors the image as
-          required, and no client processing is required - so we report 
-          no orientation. Orientations 5-8 require rotations which would 
-          swap the width and height of the image. libtiff does not do this. 
-          Instead it interprets orientations 5-8 the same as 1-4. 
-          See http://bugzilla.remotesensing.org/show_bug.cgi?id=1548.
-          To correct for this, the client must apply the transform normally
-          used for orientation 5 to both orientations 5 and 7, and apply
-          the transform normally used for orientation 7 for both
-          orientations 6 and 8. Then everythings works out OK! */
