Author: alexcher

New Revision: 8198

Modified:
   trunk/gs/src/gxclrast.c
Log:
Fix command list-based devices on 64-bit platforms. Ghostscript always writes
int values to the command list but old code interpreted the bit pattern as a
long int, causing conversion of the negative values to large positive ones.
Bug 689353.

DIFFERENCES:
None on 32-bit platforms.
