Many of the functions have bugs; for example, when drawing an outlined
polygon, the source image will not be aligned correctly.
There are also assorted /* XXX This is a dirty hack. */ comments

the week. Apart from the unimplemented window management functions,
some parts of the code will likely misbehave when confronted with
multiple clients. The 9p server itself won't have any trouble, but,
higher up, the sharing of screens and images between clients is not
