% Measure the Spd of a series of monitor settings.
%
% This routine is specific to go with CalibrateMon,
% as it depends on the action of SetMon.
%
% If whichMeterType is passed and set to 0, then the routine
% returns random spectra. This is useful for testing when
% you don't have a meter.
%
% Other valid types: See list in 'help CMCheckInit' for various Photo Research
% PR-xxx colormeters.
%
% 10/26/93 dhb Wrote it based on ccc code.
% 11/12/93 dhb Modified to use SetColor.
% 8/11/94 dhb Sync mode.
% 8/15/94 dhb Sync mode as argument, allow S to be [] for default.
% 4/12/97 dhb New toolbox compatibility, take window and bits args.
% 8/26/97 dhb pbe Add noMeterAvail arg.
% 4/7/99 dhb Add argument for radius board. Compact default arg code.
% 8/14/00 dhb Call to CMETER('SetParams') conditional on OS9.
% 8/20/00 dhb Remove bits arg to SetColor.
% 8/21/00 dhb Remove dependence on RADIUS flag. This is now handled inside of SetColor.
% dhb Change calling conventions to remove unused args.
% 9/14/00 dhb Sync mode is not actually used. Arg still passed for backwards compat.
% 2/27/02 dhb Change noMeterAvail to whichMeterType.
% 8/19/12 mk Rewrite g_usebitspp path to use PTB imaging pipeline for higher robustness
% and to support more display devices.
% 6/30/23 mk Use new clut mapping to fix this mess on standard gpus.
