This is part of the fix for 687055. This change splits the DeviceN
parameter handling. The SeparationOrder parameter handling is split
into a separate routine.
DETAILS:
The DeviceN parameter SeparationOrder is used to select which separations
are to be included in the output. This parameter is not appropriate for
high level devices like pdfwrite. The pdfwrite device does not attempt
to separate its output into separations. However the pdfwrite device
does use its process color model colors for specifying output colors in
some backup cases. If a separation were missing then the it would create
an incorrect output color. By splitting out the SeparationOrder parameter
we can still use common routines for pdfwrite and other DeviceN output
devices.
