The Distortion functions perform non-linear transformation to the texture, like twisting or shifting by a wave function.

Here is a list of the Distortion functions:

	Displace	Shift columns and lines by a projections.
	Ellipse	Magnifying glass and contraction.
	Gravimetric	Distort with a secondary texture.
	Reflection	Reflect at a secondary texture.
	Refraction	Simulate the texture under water.
	Script	Distort any way you want.
	Stretch	Contract or expand the texture to a free direction.
	Tilt	Shift by a triangle waveform.
	Twirl	Microscopic twisting for fluid effects.
	Twist	Rotate around the center.
	Wave	Shift columns and lines with a sinus waveform.
