Most patterns are centred at <0,0,0>, not <.5,.5,0>. 

Note that if you paint checker onto "box {<0,0,0><1,1,1>}" all the faces
are single colours, so I claim that's only a quarter of the checker
pattern. The repeat unit of the checker pattern is the unit cube, not
the <0,0,0><1,1,1> cube.

The gradient pattern is a bit of an oddity, particularly now that it has
recently been redesigned.
