Test gradient stop rules. Including: No stops, like fill = none. One stop, like fill = black. If a stop less than all previous stops, it is set equal to the largest stop. If two stops are equal the last stop controls the color at the overlap point.

The top rectangle must have a red outline and no fill. The middle rectabgle must have a solid black fill. The lower rectangle must have a red to green linear gradient on the left-hand galf and a solid blue fiill for the right hand half.
