That's an excellent suggestion.
And the code is really close. The only change you want is to eliminate
those two calls to cairo_close_path, (and add some underscores), giving:
Although in this specific case there probably wouldn't be a noticeable
effect, the cairo_close_path calls could get quite confusing in other
cases. What cairo_close_path does is add another line_to segment from
the current point back to the initial point of the current subpath, (and
add a join there so there are no caps).
It looks like Dirk was thinking it did "end the current subpath", but it
doesn't, (and cairo_move_to does do "begin a new subpath", so there's no
"end the current subpath" call needed).
I hope that helps,
