Indicates that a clip is intended to be used as a mask input
Set this property on any clip which will only ever have single channel alpha images fetched from it. Typically on an optional clip such as a junk matte in a keyer.
This property acts as a hint to hosts indicating that they could feed the effect from a rotoshape (or similar) rather than an 'ordinary' clip.
