CheckPaint(COLOR [, ANNO])

=s paint

checks packets' paint annotation

=d

Checks that incoming packets have paint annotation equal to COLOR. If their
paints are not equal to COLOR, then they are dropped or emitted on output 1,
depending on how many outputs were used.

CheckPaint uses the packet's PAINT annotation by default, but the ANNO
argument can specify any one-byte annotation.
