transform-origin should not accept 4 lengths

[Eric Willigers]

transform-origin accepts 1, 2, or 3 values.

Unfortunately, WebKit allows '1px 2px 3px 4x' and silently discards the last length.

I think the range.atEnd() check should move inside consumeTransformOrigin().

Ok, I will move the range.atEnd() into consumeTransformOrigin().
