[Gregory Montoir]

Update of /cvsroot/scummvm/scummvm/scumm
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv6113

Modified Files:
	gfx.cpp 
Log Message:
clip the 'top' argument in Gdi::resetBackground (as we do for bottom), this is safer and should prevent crashes when loading savegames with 'invalid' coordinates for the actors. See also bug #1252714.
