Inverse background feathering

[pd431]

Issue I face
Currently, turning on silouhette feathering digs into my silouhette. Teams does a much better job at blending the environment because it feathers outwards instead of inwards. This means the removed background can be blurred with the virtual background, instead of my body's edge being blended with the virtual background

Proposed solution

Offer a toggle (or change the behaviour) for feathering to be applied to the mask, rather than what is kept, resulting in sharper silouhette edges.

Possible alternatives

if feathering inwards is a requirement, possibly have a slider for the distance from which to apply the inwards feathering, so a halo of current background gets preserved
