Holds all of the state required to output a page of raster with libtiff.
An instance of this structure is created by LIBTIFF_RASTER_start(), and then passed back as an opaque RASTER_handle pointer. It is subsequently passed back into each LIBTIFF_RASTER_write_data() call, and finally to LIBTIFF_RASTER_finish(). Both of those functions cast the opaque pointer back to LIBTIFF_RASTER_handle, and LIBTIFF_RASTER_finish() will end by freeing the structure. In a multi-page job, no state is remembered between pages. The output of each page is a completely separate activity, implemented as a separate set of calls to the libtiff library.
Like most raster handling functions, the libtiff back-end makes use of the Core RIP Device Interface (see swdevice.h), so that the bytes of output data can be sent to any destination. The DEVICELIST and DEVICE_FILEDESCRIPTOR members refer to the output destination.
