Fix Shape stroke color when changing alpha from 0 to non-0

The handling of the stroke color lacks the extra checks that are
performed when setting the fill color. Switching from "transparent"
to another color involves setting not just the color-dirty flag but
also the geometry-dirty since alpha == 0 may skip operations such as
triangulating, meaning the work has to be performed later when once
again switching to an alpha > 0 color.
