    Fix 're' command to draw the rectangle in the other order
    
    Should draw it counter-clockwise instead of clockwise, as per PDF spec.
    
    This was causing bugs on files such as fts_14_1408.pdf
    
    I also changed it to use rlineto instead of lineto, because it seems
    slightly more efficient.  Now it matches the gs implementation that also
    uses rlineto.

    Change pdf implementation to use CalGray and CalRGB
    
    It was previously mapping these to DeviceGray and DeviceRGB for some
    reason.
    
    See tests_private/pdf/PDF_1.7_FTS/fts_08_0829.pdf for example where this
    matters.
