Update of /cvs/ghostscript/gs/lib
In directory casper:/tmp/cvs-serv26172/lib

Modified Files:
	gs_setpd.ps 
Log Message:
Fix: Adobe renders marks outside the ImagingBBox and QuarkXPress relies
on this. Maintain the ImagingBBox of the page device at the PostScript
level independently from the device parameter. There is a slight
incompatibility if programs that set the ImagingBBox incorrectly relied
on this causing clipping, which is prohibited by the PLRM. Programs that
wish to directly set the ImagingBBox device parameter can still do so
from C or from PS using the .putdeviceprops GS private operator.
Fixes SF bug 570829 for Artifex customer #411.
