draw_arc styles missing?

[harpoonlobotomy]

I've spent a decent few hours on this today, I'll admit.

In both the docs and the docstring, this list is given - 'pieslice', 'chord', 'arc', 'first', 'last', 'butt', 'projecting', 'round', 'bevel', 'miter' - as valid styles for Graph.draw_arc.

But, using anything other than arc, chord or pieslice gives the following error:

Error encountered drawing arc. bad -style option "bevel": must be arc, chord, or pieslice

Looking it up, plenty of places online give this list as the valid list of styles, but I've not found anyone talking about them not working - so it's entirely possible I'm missing something very obvious. My google-fu has failed to yield much of anything, so I figured I'd ask here.

The error is triggered here:

return self.tk.getint(self.tk.call(self._w, 'create', itemType, *(args + le_options))), around ln 3010 in tkinter \ __init__.py, via FreeSimpleGui \ elements \ graph.py's Graph.draw_arc(), and the only thing I can't gather is where in FSGui or TK the arc, chord, pieslice shortlist is pulled from.

But, on a related note -- I did find something curious - does FSGui use PIL to draw its arcs?

(I'm aware this is a bit of a ramble, I've been neck deep in site-packages on no sleep for a little too long, hah.)
