New Revision: 7159

Modified:
   trunk/gs/src/gsccolor.h
   trunk/gs/src/gsfunc4.c
Log:
Increase the number of DeviceN components we can handle to at least
250 (which is needed by CET 09-03, 09-06, ...). Both GS_CLIENT_COLOR_MAX_COMPONENTS
and MAX_VSTACK depth are needed since we use Type 4 functions to handle DeviceN colors.
