Effect: Mask Tweak

Description
Allows for the fine tuning of a mask. Often an extracted mask needs tweaking before it will give the desired result in a compositing operation. This effect assumes that the mask is a grayscale clip.

Controls

Choke:		Shrinks the edges of a mask and makes those edges harder.
Feather:		Softens the edges of a mask without making them grow.
Boost:		Multiplies the intensity of the mask, making it brighter.
