Hi everyone. I want to know if nowadays (2020) Metafun is able to do an
actual unfill, like above:
https://tex.stackexchange.com/questions/151068/how-can-i-fill-a-complex-path-with-metapost-metafun/218718#218718
Example of what I want to do:
\startMPpage
path A, B, C;
A := unitcircle shifted (-center unitcircle);
A := A scaled 4cm;
B := unitcircle shifted (-center unitcircle);
B := B scaled 1cm;
%C := (reverse B) shifted (left*1.4cm);
%It works for two paths
fill (reverse B)-- A -- cycle withcolor red;
%fill A -- (reverse B) -- C -- cycle withcolor red;
%When I try the same with three paths, a thin, unwanted line appears
\stopMPpage
I'm aware of unfill and I've read somewhere else about using pens instead,
but I want to know if a better solution is possible. Thank you in advance.
Regards,
Jairo :)

\startMPpage
path A; A := (unitcircle shifted (-center unitcircle)) scaled 4cm;
path B; B := (unitcircle shifted (-center unitcircle)) scaled 1cm;
path C; C := B shifted (left*1.4cm);
nofill A; nofill B; eofill C;
\stopMPpage

Oh, cool. I've found some info in the Metafun manual too. I should read
more carefully next time.
Thank you very much!
