New Revision: 8851

Modified:
   trunk/gs/src/gxpcmap.c
Log:
Increase the default threshold for using the (much slower) pattern clist accumulator.
The 32Mb threshold is tolerable for most host systems and this can be modified during
the build with -DMAX_PATTERN_BITMAP_SIZE=___ (possibly using the makefile XCFLAGS).

Only embedded systems may want to set this to a smaller value.

This is a temnporary workaround for bug 689966. Improving the performance of the
pattern clist accumulator will be considered a future enhancement.
