Hi,

If you change 

drawdot (0,0) withpen pencircle scaled 8pt withcolor red;

into

drawdot (6pt,6pt) withpen pencircle scaled 8pt withcolor red ;

you get what you want (at least for the red dot on the lower left corner).

Here 6pt = 2pt (with of the pen used for the frame) + 4pt (half the diameter of the pen used for the dot).

Best regards: Otared
