status.i4.v = snp_setup(plot_info.s.r [,top_row.i4.v]

	This routine allows a user to edit a snapshot plot setup.

	plot_info	plot information structure (type is SNP_INFO)
	[top_row]	top row of snapshot window (default is WMNGR_CENTER)
	[left_column]	left column of snapshot window (default is WMNGR_CENTER)

	This function returns status values as follows:

	CBS_WINDOW_TOO_BIG	plot window won't fit on screen
	TRUE			plot setup was changed
	FALSE			plot setup was not changed

	This function requires the following include files:

	cnsparam_h, cns_data_structs_h, cbslib_h, acnet_errors_h
