Yes it is.

You can't draw semi opaque area's (afaik), but I guess you can fake it.

- You draw the area "Out" (in green)
- You draw the area "In" in front of it (in orange)
- You draw the area "smallest of (In, Out)" in front of it (in an
orange-green mixed color)
- You draw the line "Out" in front of it
- You draw the line "In" in front of it


All done from head, so I may have made some mistakes.
It might just work though.


P.s. the colorful background can be done too, just draw some area's in
front of each other, each with a different color blue.
