Some examples pass four parameters

[JacobChrist]

Describe the issue
Some examples pass four parameters to the ez.SetXY() but the third and fourth parameter are not documented in the ezLCD-5x LUA API Manual 082922

	---- gasguage.lua 
	ez.Cls(0,0,0)
	delay  = 100	-- set frame delay in milliseconds
	for loop = 1,5,1 -- show it a 10 times
	do
		for image = 20,49,1  -- 0,3 does bmp files 4,7 does jpg as set in config.txt
		do
			ez.SetXY(0,0,0,0)	-- set graphic start location
			ez.PutPictNo(image) -- draw image n (can be bmp or jpg) jpg will be much faster
			ez.Wait_ms(delay)	-- delay display of next frame
			image = image + 1
		end
		for image = 49,20,-1  -- 0,3 does bmp files 4,7 does jpg as set in config.txt
		do
				ez.SetXY(0,0,0,0)	-- set graphic start location
				ez.PutPictNo(image) -- draw image n (can be bmp or jpg) jpg will be much faster
				ez.Wait_ms(delay)	-- delay display of next frame
				image = image + 1
		end
	end

We should fix the manual or the example code (autoexec.lua)
