That is a ‘little’ above my current state of knowledge. But I think it
will be an interesting read.


I have made an initial routine to draw a stick man:
    % Places a stickman at x, y. Two units wide, seven units high.
    /stickman { % x y unit
        3 dict begin
            /unit exch def
            /y    exch def
            /x    exch def
    
            gsave
            newpath
            % start top center
            x unit add  y unit 7 mul add  translate
            % draw head
            0  unit neg  unit  0  360  arc closepath
            % draw body
            0  unit 2 mul neg  moveto
            0  unit 6 mul neg  lineto
            % draw arms
            unit neg  unit 3 mul neg  moveto
            0         unit 4 mul neg  lineto
            unit      unit 3 mul neg  lineto
            % draw legs
            unit neg  unit 7 mul neg  moveto
            0         unit 6 mul neg  lineto
            unit      unit 7 mul neg  lineto
    
            stroke
            grestore
        end
    } def

I would not mind feedback on it. :-D For example: are the ratios
correct?


By the way, I want to expand this function, so that I can draw a range
of stick mans:
    - the default one
    - happy one
    - angry one
    - sad one
    - kneeling
    - …

What is the best way to do this? I mean graphically, but also
programmatically: how to write it so it is easy to use.
