Sure. Doesn't a gradient x pattern coorespond to 0*x to 1*x and then repeat
at 1 unit intervals? Of course it does. However not all patterns are of a
linear nature to measure like that one, which is what I said. So that the
pattern defaults to 1 unit until rescaled.

Very imprecise description I gave there, sorry.
