New Revision: 8334

Modified:
   trunk/gs/doc/Use.htm
   trunk/gs/src/gsalphac.c
   trunk/gs/src/gsovrc.c
   trunk/gs/src/gsropc.c
   trunk/gs/src/gxclrast.c
Log:
Fix (banding) : Improving the debug trace about compositors.

DETAILS :

This change is algorithmically equivalent for release build.
In the debug build it only adds more debug printing.

1. Added a debug printing for alpha, overprint and rop compositors
when writing/reading from/to clist.

2. (gxclrast.c) When printing a matrix with the 'L' switch,
use global page coordinates as rectangle operations do.
It allows to map reading operatrions to corresponding writeing operations.
  
EXPECTED DIFFERENCES :

None.
