Re: draw rectangle with lines, filling problem

Only the line-to calls produce an edge to the filled shape. The moveto 
calls start new filled shapes (or produce nothing if they are just a 
point or 1 line).

You probably want to draw the rectangle with 4 sides to fill it, then 
add your line segments afterwards.
