Well, you can do shapes easily enough just by connecting
the dots. For example, in AnnotateWindow you can choose
a pencil cursor and draw whatever shape you like (if you
have any drawing talent, of course). You just can't get
ALL the points the cursor crosses over. I don't think
object graphics will help in this case, either. You will
have learned them for nothing. :-)
Cheers,

P.S. Even using the pencil tool in something like Photoshop
you see that if you move your pencil fast you get a straight
line, while if you move it slowly you can get a nice even
bend in the line. I think this is a function of your
medium (a computer) and not a function of your art skills.
