\function{degrees()}, which takes an optional argument letting
you specify the number of units corresponding to a full circle:
-\begin{methoddesc}{degrees}{\optional{fullcircle}}
+\begin{methoddesc}[Turtle]{degrees}{\optional{fullcircle}}
\var{fullcircle} is by default 360. This can cause the pen to have any
angular units whatever: give \var{fullcircle} 2*$\pi$ for radians, or
400 for gradians.
