Needless to say render and parse time can be very long, thus making it slow
to experiment with the post processes. With a copy{} object one could output
several different versions of the file:
post_process {
copy { png "no_postprocess.png" }
copy { png "focal_and_soft.png"
focal_blur{10,5,2}
soft_glow{.6,5}
}
}
