Print text to screen during calibrations

[k1o0]

It would be nice to print to info to the PTB window during gamma correction and water calibration. This would help users who don't have an auxiliary screen on their stimulus rig. Currently the information is printed to the command window and is therefore not visible.

Can be done through Window object

Rigbox/+hw/+ptb/Window.m

Line 387 in c98a247

function [nx, ny] = drawText(obj, text, x, y, colour, vSpacing, wrapAt)

[k1o0]

This text should be printed to the screen:

Rigbox/+srv/expServer.m

Lines 359 to 367 in c98a247

	function calibrateGamma()
	stimWindow = rig.stimWindow;
	DaqDev = rig.daqController.DaqIds;
	lightIn = 'ai0'; % defaults from hw.psy.Window
	clockIn = 'ai1';
	clockOut = 'port1/line0 (PFI4)';
	log(['Please connect photodiode to %s, clockIn to %s and clockOut to %s.\r'...
	'Press any key to contiue\n'],lightIn,clockIn,clockOut);
	pause; % wait for keypress
