Draw a polygon with it's origin (0,0) at the screen position (x,y).
Optionally scale (re-size) it by the decimal scale where 1 is full
size. Also you may also rotate the stamp clockwise around it's
origin by specifying how far to rotate as an angle expressed in
radians (0 to 2p).

Radians 0 to 2p

Angles in BASIC-256 are expressed in a unit of measure known as
a radian. Radians range from 0 to 2p. A right angle is p/2 radians
and an about face is p radians. You can convert degrees to
radians with the formula r=d /180∗ .
