visual effect push left to black

# Description

Use the black keyword to transition to a blank black background in a sequence of visual effects.

Visual effects can be stacked in a sequence by using several visual effect commands in succession. If the last transition ends with showing the card, and all except the last one shows an intermediate image (such as a solid black color), the effect is enhanced. You show a solid black color at the end of a transition by using the black keyword.

This example uses the push effect with the black keyword to emulate an old-fashioned slide projector:

visual effect push left to black -- from card to solid black visual effect push right to card -- from black to final card go card "Destination"
