The attached file contains the proposal for 

(1) a new circle method (here called circle2)
(2) a new circle function (also called circle2)

Moreover it contains a testscript showing the
respective3 filling behaviour.

Visually they behave differently and it may well
be a point of discussion if this replacement
schould be made.

circle2 has correct filling behaviour and doesn't
show the strange 'not drawing feature' after a
radians() call.

All the other problems with radians()/degrees()
remain. (see #1514685)
