object pigment is a block pigment, in a way, similar to checker. It 
demand 2 pigments or textures: The first to be used inside the reference 
object, and the second to be used outside.
It's used on an object larger than the controll object.
A use would be to add some text to an object, that text been controled 
by a text object. You can then use a warp to have that text warp around 
some object.
