[STR New]

cupsfilter.c reads the cupsd.conf parameter "RIPCache" and sets it into an
environment variable RIP_CACHE. This is not quite right.

ghostscript uses an environment variable RIP_MAX_CACHE, rather than one
called RIP_CACHE, to set the size of the raster image processor cache.

cupsfilter.c should set the RIP_MAX_CACHE environment variable, rather
than the RIP_CACHE environment variable.

job.c does the correct thing (see line 879 of scheduler/job.c) when
processing a job through the cups filter chain.

A patch is attached for cupsfilter.c, against the cups-1.4.x branch.
