adjustable parameters.
@item Source Masks allow an existing OBS source to be used as a mask, using
any combination of the red, green, blue, or alpha channels from said source.
@item Image Masks include all of the same functionality as Source Masks, but
applied via a static image (.png, .jpeg, etc).
