useOverscan globals.compDefaults.useOverscan Sets whether to use upstream overscan (if available)
during the border extension process. If overscan is
available (and of usable quality), this typically yields
superior results around frame edges.
However, if you are unsure of this procedure or the
integrity of overscanned areas is unknown, it's safer to
leave this disabled.
Overscan refers to image pixel data outside of the
displayWindow and can be inspected using options in
the Monitor.
For information on explicitly manipulating these
regions, see the ImageCrop node.
