Performs the SSAO pass.

| renderer |

The renderer.

| | writeBuffer |

The write buffer. This buffer is intended as the rendering destination for the pass.

| | readBuffer |

The read buffer. The pass can access the result from the previous pass from this buffer.

| | deltaTime |

The delta time in seconds.

| | maskActive |

Whether masking is active or not.
