[Bf-committers] Uniform displace modifier patch

[Campbell Barton]

The reason I kept the mid level is to follow `the rule of least
surprise` for users,
So a blank texture always works the same as a white image and users
dont need to think about mid level's use changing when they set/clear
a  texture.
