AutoVisual/IGPFamily.pde: Fixing NullPointerException in

setStrokeColor() and setFillColor(). Adding useStrokeColor() and
useFillColor() to all drawing operations. Colorization now has to be set
prior to drawing the element by calling setStrokeColor() and/or
setFillColor() with a Float[] containing RGBA values.
