Blending Curves
Blend curves are used to adjust the blend of the front and back elements by
adjusting the amount of fractional opacity (pixel area) for the front, and one
minus front. The latter gives more importance to the back. Blend curves is
useful for controlling the blend along the edges of a matte by adjusting
fractional values, not 0 and 1 values. Because mattes have fractional values
along the edges, the blend curves affect the edge blending.
