[issue1513695] new turtle module

[Gregor Lingl]

In my last posting i forgot a fourth proposition.

Currently one has the Turtle.methods fill(), begin_fill() and end_fill()
As is stated in the old turtle docs the specification of fill is "rather
complex". begin_fill() and end_fill(), are identical to fill(True) and
fill(False) (or fill(1) and fill(0)). That means, that begin_fill()
sometimes may do somthing unexpected, namely complete som filling
underway. In the new turtle module fill() without arguments returns the
filling state, i. e. True/False respectively.

I'd prefer the following:

begin_fill() should only start a new filling process and cancel some
underway, if necessary (that means: a filling without end_fill will
not take place) 

end_fill() should only complete the current filling process

a new method filling() should be used to ask if same filling is
currently taking place

and fill() could be dropped. (deprecated in 2.6)

I think Vern Ceders intention with introducing begin_fill and end_fill
was to have a clear and easily understandable meaning, which is only
partially accomplished with the current solution.

What is your opinion?
Gregor
