[gs-cvs] rev 8765 - trunk/gs/src

New Revision: 8765

Modified:
   trunk/gs/src/gsiparam.h
Log:
Reduce the GS_IMAGE_MAX_PLANES to a sane number. The image cannot have more
planes than the number of CLIENT_COLORS we support (plus 1 for alpha).
This cures a stack overflow seen with the multi-threaded rendering on
Windows.
