Hi, I got a problem in metapost. If I want to draw a ring, and
use the code:
fill fullcircle scaled 2cm ;
unfill fullcircle scaled 1cm ;
The inner part is not transparent, it has the color of "background"
variable which is "white" by default.
This case is a minimal example, I actually wanna draw something
more complex, like the glyph "Q" and I know the inner path and
outer path. How can I fill the ring without jeopardizing the area inside
the inner path?

Best Regards
Chen
