I think am kind of getting this.. the idea is derive a class from fl widget, so
then my own class which say calls an fl_box into being
can then use the box as it's 'drawing canvas' by calling the inherited
draw function from the widget class.
Whenever i wanted to draw the rectangle i could just call
myClass.draw(x,y,w,h) ??
