For example, adjusting the symmetry will allow you to change a circle into an ellipse.
Symmetry can be adjusted using the z axis of the joystick.
Position If the wipe pattern has positioning then the joystick on the external panel or the x
position: and y position: boxes in the transition palette of the software control panel
can be used to move the center of the pattern. Moving the joystick dynamically
updates the x and y position display in the software control panel.
