patch for zcolor.c indexed color space handling.

Description Ken Sharp 2009-10-20 03:49:22 UTC 
While testing PCL->ps2write conversion I came up with this file, its the output
of ps2write. When run through a debug version of GS, using a debugger, it
produces a number of warnings of the form:

".\psi\igcstr.c(153): String pointer 0x....[768] outside [0x...0x...)"

When a debug version is run from teh command line the warnings occur followed by
a GPF (SEGV). The release version just gives a SEGV.

The call stack :

gc_string_mark()
gc_trace()
gs_gc_reclaim()
context_reclaim()
gs_vmreclaim()
ireclaim()
interp_reclaim()


The file runs normally through Acrobat Distiller and through Jaws, so I think
this is a genuine GS memory problem, but it is conceivable that the file is
incorrect.

patch for zcolor.c indexed color space handling.

This patch mirrors in the PS world what the PXL code does to create its equivalent of a indexed colour space with a lookup table in a string - see pxgstate.c around line 373-386.
