How to create a circle or any other shape whose perimeter line is cased? That is the stroke has it's own interior fill and bounding line in addition to the shape having fill?
I can simulate it by stacking 2 circles, with the inner circle smaller and centre occluding the outer circle, but this is extra work and grows less and less feasible on complex shapes. I was hoping to find a line/stroke style that does this all in one go, leaving the objects as single entities.
These example shapes are visually correct, but they're they're result of drawing, duplicating, resizing and then grouping multiple objects.
Another phrasing of this question: How to create a stroke paint that is smaller or with an inner offset to it's stroke style?
