Text's stroke property actually strokes the text, rather than overwriting the fill

When assigning a stroke to a Text it was filling the shape and then layering the stroke on top. The assumed nature of a stroke is to be around the text rather than overwriting it, so I've ensured that ```stroke()``` is called before ```fill()```.
