I am not sure what the reporter is asking for - if he is asking if 
the hack CUPS_RASTER_WRITE/CUPS_RASTER_WRITE_COMPRESSED will break other cups
devices, I don't think anybody is spending any time doing that test. As for
make it possible to do compressed raster version 2 and for making it runtime
selectable, the cups device supports a "cupsCompression" option, which can
probably be used for that purpose, but it does not seems to be hooked up to any
internal machinery at the moment.

The pdftoraster tool seems to run with -dcupsCompression=...

The original reporter is well-comed to submit a well-tested patch, but until
then, it is unlikely for anybody to be spending much time on this request.
Please re-open if such a patch is available.

Till : can you comment on what the cupsCompression option does (and whether it
has any effect)?
