Modifying the wipe pattern
You can modify wipe patterns in the following ways. The block-capital
expressions in parenthesis show how the modification is indicated on the
menu screen.
Wipe direction (DIRECTION): The wipe can proceed in the forward
("normal") direction, or the reverse direction. There is also an
alternating option, in which the wipe direction reverses each time it is
executed.
Pattern positioning (POSITIONER): When this function is enabled, you
can alter the position of the pattern in video space.
