What I want SOURCE for is to set the destination (within a shape) to a
known alpha value (other than 0.0 or 1.0) without respect to the
existing content of the destination.
OVER does not allow this.
And the current implementation doesn't make this easy since SOURCE has
the additional effect of clearing the destination in the area between
my shape and the clip.
