\Standard I-Tex offers you two standard line functions. Adjust the line thickness with the Pen Size parameter.
	Solid This function draws a line over the background using the primary color. If you set the opacity value to lower than 100 the line will blend with the texture.

	\Special In addition to the standard lines, there are three special line functions which can produce some interesting effects.
	Fractal Two points are connected as in a normal line, but the fractal line does not take a direct route.

	\Tear This are the tear functions.
	Tear Using the tear function you can draw irregular tears with the primary color on the texture and create natural-looking surfaces.
	Branching Tear This function is similar to the tear function, but the tear is branched several times during the drawing process. You can simulate branches on the ground of a forest using this function.
