QLiss3D - Lissajous Figures

		This is the graph of a sine function. The x value is increasing continiously while the y value is the result of sin(x).
		In this picture you can see a very simple Lissajous figure. Y- and x-frequency are the same. Both x- and y-values of the painted pixels are results of sin(i), where i is an increasing counting variable.
		Here the x-frequency is twice as high as the y-frequency and the resulting Lissajous figure consists of points with the coordinates (sin(2i)|sin(i)).
